what do you need ?

I want to call withdraw function on bridge smartcontract with golang I don't have any example how to call a function from golang I saw how you are able to create a transaction and sign it, but it won't help me I need to be able to create the call with params, and sign this Please can you give me any golang code example with a call to smartcontract function?

a smart contract call is just a regular tx, just with higher gas limit and with the function name and parameters encoded in the data field
