I'm trying to create an ERC20 token. Where do I find the best and clearest resources that could help me with some specific functionalities I want written into the smart contract? Thank you!

I'm not a developer, using youtube and chatgpt so far (latter is useless), doing it in vs code with hardhat. I'm aware of openzeppelin, I'm using its erc20 contract, but wanting to add some additional functionalities, and I'm just not sure how, there aren't clear enough tutorials on youtube, and I'm not sure where to go for specific help.

Many thanks to anyone who can give me some pointers.
