Get List Of All Tags
Returns a list of all tags in a vault, sorted alphabetically.
Most of the time you would use this action to get the full list of tags, then loop over the results list using the built-in "Repeat With" block and filter them with whatever you need. The loop variable
Repeat Item will contain a single tag.
If you want to filter the list, I recommend using the "Filter List" action from Sindre Sorhus's excellent Actions app (no relation) or a built-in "Repeat With" loop with a contained "If" action.
