Can anyone recommend any references on how to build a contract that can cover the gas fees

what does it mean "cover gas fees" ?

I mean the transaction should be free for the person performing the transaction, but the gas fees should still be paid by the contract that is invoked

For eg. When we mint an NFT on opensea or rarible for free

How to build something like that?

Look at Ethereum gasless transactions. I think it’s technically possible though I haven’t played with it

Search about meta transactions

Opengsn

be careful with trustedForwarder or will do the same end of crosswise😂

Crosswise did a stupid mistake. Trustedforwarder is usually secure

check anyswap
