Please remove set from Polygon sets

[gabrielfior]

As seen in PR (https://github.com/SetProtocol/uniswap-tokenlist/pull/157), I tried to delete the reference to the Polygon set we opened before. We want to remove this fund as we are not maintaining it anymore and will not use that at all in the future. However, the fund is still accessible via the Tokensets UI (https://www.tokensets.com/v2/set/polygon/0x7F73CE42963fB967dF88d8815f364DCc47F1Ea89).

Can you please advise on how to PERMANENTLY REMOVE this set from Tokensets? Thanks, Gabriel
