How to call functions of the ERC20 smart contracts like transferFrom, mint burn or other custom interfaces

Are there any API that i can use to call other functionalities of ERC20 smart contract like transferFrom ? Most probably we will use FireBlocks custodian to take over ownership of the smart contract and then we will need APIs to call standard functionalities like transferFrom, mint or burn or other custom functionalities

I have call the write function in smart contract but my transaction are not complete, stuck on BROADCASTING
fireblocks-web3-provider:status Fireblocks transaction tx_id changed status from SUBMITTED to QUEUED +0ms
fireblocks-web3-provider:status Fireblocks transaction tx_id changed status from QUEUED to PENDING_SIGNATURE +3s
fireblocks-web3-provider:status Fireblocks transaction tx_id changed status from PENDING_SIGNATURE to BROADCASTING +3s
what’s the issue?
