The original issue on Github was this one: [NPoS] Nomination pools: Allow funds to be used for democracy · Issue #454 · paritytech/polkadot-sdk · GitHub
That one is closed now, and I think this is the new one for follow-on work: [Pools] Follow up issues/improvements for Pools open gov integration · Issue #4404 · paritytech/polkadot-sdk · GitHub
