And the link valid the transaction on The Pool on Pancanke Swap directly in "THETOKEN" ... (NOT WITH ETH, NOT WITH BTC, NOT WITH CONVERSION , without intermediaries (CRYPTO.COM & BITPAY & CO OR if you take an intermediary, I don't want them to offer a direct transaction in BTC / ETH.))
That is not possible, even if it is, that didn't match the requirement of no intermediaries and no conversion.
How simply do you do that ?
I believe there is no such simple plugin or application to meet your criteria. At least there is no ready-to-go payment processors, unless you want use a third-party service. I see that BTCPay support altcoin payment that it offer ETH 20 based tokens, if you want to do it your own, I think you should/can use it as a start to develop the BEP20 payment processors.
