So I want tu understand well how does it work and ... @curvefi

If you want to withdraw your USDC/MAI/USDT tokens from the pool and have them back on your wallet, you need to unstake them first. This can be done by going to the pool page and clicking on the “Unstake” button. Once you have done that, your tokens will be transferred back to your wallet in their original form, i.e. USDC/MAI/USDT tokens. You will not receive LP tokens. It is important to note that once you have unstaked your tokens, you may need to wait for a certain amount of time for the transaction to be completed.

yeah, you want to withdraw from the pool the unstaked part? or all your liquidity ?
