Hi @DavidMcCarter-5256, yes Logic App is one way to do it. You can try below steps to get the desired result through Azure Logic App:
1) Create New Logic App and provide a primary connection account:
2) Configure the next step in workflow by getting the usernames from all documents in collection. It will be good idea to save the username with '@' prefix, so to match the twitter account names:
3) Then we need to create another step and loop through the result set from prior step as below:
4) Finally, we can write the result by creating another document in the 'For Each' container.
Please let me know if this helps or any other information is needed.
