Impossible to cancel bitcoin or cryto transaction once you sent the payment or bitcoin you just have to wait until it confirms your transaction. There is no way to cancel it.
I agree with what you said brother, it is true that a transaction can not be canceled at any bitcoin wallet. Once you sent a Bitcoin you can do nothing but wait whether you like it or not, even if you make a mistake. unless you contact their services that you want to cancel the transaction. you're lucky if they approve your "cancel" request.
