How to withdraw from a very old smart contract?

It's an old liquidity pool from 1inch from years ago.

The contract is: https://etherscan.io/token/0x7566126f2fd0f2dddae01bb8a6ea49b760383d5a?a=0xb910b6e7d5b7e703e47a56f697b65a3dfe7cc355#writeContract

I've tried using the 1inch gui but am having no luck. Can I withdraw direct from etherscan.io. I've got it on metamask for now if that helps. But I'm a total newbie and have never done anything like this apart from using a Gui.

Any help is appreciated.
