Hello guys. I have a crowdsale contract which creates an erc20 token and sells it simultaneously. So my erc20 token is created by another contract, not msg.sender. My question is, how will I access functions in the erc20 contract?

Should I use call or delegatecall?

Normally, it's like any other contract. Only if you have functionality which requires some sort of owner access then the owner is probably the contract so that has to execute such functionalities

But I can't directly access functions in erc20 contract

The erc20 contract is created by crowdsale contract

I can access only functions in crowdsale

It doesn't matter who creates a contract unless you have coded some functionality there which depends on msg.sender
