Remove People from a cell with multiple people

I’ve created a Subscribe button in my doc that enables users to receive Slack DMs when an update is made to a specific row. My table now has a column called Followers, which will be multiple people, and each of those people will receive Slack DMs when that row is updated.

I now need to build a unsubscribe button to let users turn off their DMs when they no long want updates. The formula should essentially just strip the User() from the list of others users within the cell but I’m struggling to make this happen - would love it if anyone has ideas!

Hi Chris,
