How to pay from the contract for the user's gas? To make operation free for user wallet?

How to user can make operation frоm wallet with free for gas per operation? To make payment from smart contract wallet for example?
Is there such a possibility? If is there, how roughly will this work?
I am looking at the binance smart chain network.
Thanks in advance!

As far as I know, it's not posibble to fund a contract with gas to then make the calls to the contract gasless.

You have to make a meta-transaction.

Thank you! I understand correctly: for that pattern I need standalone server (not decentralized, chain-off), that will send transaction instead user?

More and less that is.
