Help with contract verification on Polygon

We deployed a contract on the polygon network late last year and have not been able to get it verified. I have tried all the steps listed here in the OpenZeppelin forum however none of the steps work.

Looking for a developer to help verify the contract.


your contract has not been verified for a long time, if for some reason I make any changes to the contracts it will be impossible to do so, I recommend using truffler to try to verify it,

wouldn't i have had to deploy it on truffle to verify it via truffle?
