This is a relatively straightforward web3 interaction in which you will call the delegate function on the GTC token contract 0xde30da39c46104798bb5aa3fe8b9e0e1f348163f.
If you're having issues delegating through the Quadratic Lands UI you can also try delegating voting power using our [Tally interface](need production link) or even with Etherscan.
