How to sell tribe on Coinbase?

Could you please provide a step-by-step guide on how to sell Tribe tokens on Coinbase? I'm interested in knowing the exact process, from logging into my account to confirming the sale and receiving the funds. Is there a specific section in the Coinbase app or website where I can find Tribe and initiate the selling process? Additionally, are there any fees associated with selling Tribe on Coinbase, and if so, how are they calculated? Lastly, is there a minimum amount of Tribe I need to have in order to sell on Coinbase, or can I sell any amount I choose? Thank you for your assistance.
