How to early withdraw from Gnosis validator node?

[mtr980]

Describe the bug
How do I perform early withdrawal from the Gnosis validator node, I am using Nethermind as the execution client and Lighthouse as the consensus client on macOS.

For some reason the beacon chain never syncs and I exit the consensus client and have a negative APR of 9% at the moment. Despite going through blog posts and community channels cannot find step by step guide on an early withdrawal.

My withdrawal credential address has a prefix of 0x00 and actually not sure how the entire withdrawal process work using the CLI commands on macOS.
