Dynamically Add Document Library Column to all User Created Libraries in SharePoint Online

Hi Everyone,

I was thinking that there is a document library column (date column) that we would like to have added to all user created Libraries on each SharePoint Online site.

I'm thinking Power Automate / Flow but I can't figure out how to do this with the right action.  Ideally, I would like for the flow to figure out all of the user libraries on the site (excludes Site Assets, for example) and then add a Date column to those Libraries called "Compliance Date" for each library that doesn't already have that column.  The flow could run once a day until my retirement!

Perhaps Flow isn't the right option.  Any help would be appreciated. 

Thanks!
