How do I use CoW swap with a proposal on decentDAO.org?

Hi CoW community,

I am from DecentDAO.org. Our clients want to manage their treasury by purchasing WBTC. After some studying, I think CoW Swap is the best approach.

Our clients can create a proposal on decentDAO.org, and can enter a tx. Are there a detailed instructions on how to invoke CoW protocol contract? I need the contract address and description of what each param means. Is GPv2Settilement the right contract to call? What are the sequence of functions that must be called?

Thanks
