If you control your webstore you may be able to put in a BCH processor for payments, like prompt.cash which also has a wordpress plugin that works great for us.

Description BitcoinCash BCH Payment Processor. Non-custodial instant payments without chargebacks. Secure and easy to implement in a 1 minute setup. Only you hold the private key to your wallet. We do not have access to it, so we can never freeze (or take) your funds. BitcoinCash (BCH) payments can't be reversed. Every payment is permanent which lets you save money on payment fraud detection. We support 0-conf for payments in less than a second. Additionally you can setup thresholds to wait for a certain amount of confirmations depending on the payment value. Your WordPress page or WooCommerce shop can accept Bitcoin Cash today with prompt.cash. https://prompt.cash

For online website https://prompt.cash/ is one option.

not just that - basically something easy to set up like a PayPal button but for non-custodial crypto payments directly to your crypto wallet i.e. you get all the features like logging payments, email notifications etc... prompt.cash gets very close to this but as far as I can see there is no option for user selectable donation amounts.

Yesterday I "lost" at least $100 (maybe $200) because I couldn't bridge to sBCH in under 2 confirmations. The rate I wanted changed after like 20 mins, and the blocks were slow. The prompt.cash bridge pretends it works in 1 confirmation, when in fact it takes 2 (a bug). What I mean is, there's no 0-conf smartBCH bridge. (I used up all that bridge's liquidity with about $9k, but they've added more. If a rate changes by 2% on $9k, that's $180 gone.)

https://prompt.cash/ was absolutely great when I tried it, highly recommended.

I'm not really familiar with this platform TBH but something like https://prompt.cash/ might be helpful to you, it will allow you to add an easy pay box to your site, though generally you will have many more options if you are self hosted with something like wordpress, then you can use plugins like cryptowoo or mycryptocheckout for multiple coins, still with no third party involvement.

It is non-custodian betting on price of supported assets paired against BCH, both parties put their money into the contract's pot and later the contract parses an oracle message and calculates how much they can take out. Made possible with Introspection opcodes and int64 upgrades to Bitcoin-tech Script VM, which activated in May '22 on Bitcoin Cash blockchain.

I dug around a bit and it seems to be this one: CHIP-2021-02-Bigger-Script-Integers.

native introspection

The latest "Group" proposal (v4.2) is more than just "tokenization". It got simpler and more powerful at the same time. It now enables generic BCH output groups that can be used to create persistent Script covenant contracts that can prove their genuineness. This is something that current contracts cannot do, even with the new Introspection opcodes. Group would make it possible because the groupID is a commitment to the whole genesis transaction, but this is not a post about that.

Will you soon shut up about BCH being shit against "superior chains" when I point you to the CHIPs such as Native Introspection Opcodes, Bigger Script Integers which allows better smart contract functionality coming in 2022, and PMv3 and Group Tokens which allow better token and transaction formats that are coming in 2023?

You can't, because it requires a sibling output (same prevout txid as the contract, but index 1 instead of 0) to be spent alongside it and it verifies it using introspection opcodes that will be available in May. Only the owner of the sibling can spend the contract.
