Need to use Search Windows in Slack and Microsoft Outlook (16.22.1) at the same time

Trying to accomplish:

To create a KBM ShortCut that will open a search window like Spotlight to search in both Search Windows at once (or with a little delay).
Is there a way to add Slack and Outlook Search Windows into Spotlight (from my poking around, I see no option in the MAC OS Settings and seen other threaded discussions saying this is not possible)?
Is there a way to add this search feature into Finder (Not sure that is possible since Finder only uses sidebar locations. Not sure you can add an app there)?

I am trying to search bug#'s in both at once to review the communication chatter on both of them at the same time.
