Google docs popping out into untabable window

I use Glide and the Google Sheet that is associate with the app is not opening in. a new tab but rather as a floating window that cannot be tabbed. Same happens when clicking email links taking me to a Google form. I suspect this behavior is related to Google Docs in general. Is there a place in Settings or other means to change this behavior so they can be set as a tabbed window. Thank you, Todd. (MacOSX Catalina 2013iMac)
