Where do find "Activity" and the "..." to import from Google Drive?

Hey there, Debra! 

I'd be happy to help and explain as much as possible.

Now, as the Help Center mentions: Dropbox is changing the way that Google Docs, Sheets, and Slides are created and stored in Dropbox. 

If you’ve created any Google Docs, Sheets, or Slides on dropbox.com, you’ll need to move or convert your files in order to maintain access to them.There are two options to do so: 

-Move the files to Google Drive (GDrive) and replace them with Dropbox shortcuts. You’ll need to sign in and link to your Google Account in order to move files to Google Drive. Once the files have been moved, you’ll still have access to those files in Dropbox, but the file will show as a .web shortcut.

-Convert the Google files (.gdoc, .gsheet, .gslide) to the equivalent Microsoft Office file formats (.docx, .xlsx, .pptx).

Now, keep in mind that if you move your files to Google Workspace: 

-No changes will be made to the file contents.
-File ownership will now be in Google, this means any sharing permissions won’t automatically be transferred to Google. You’ll need to choose if you wish to have the permissions/roles shared.
-Moving files manually to Google Drive will impact your Google storage capacity, but will also free up Dropbox storage.
-Dropbox shortcuts won’t track version history for changes made on Google Workspace.  You’ll need to use Google Workspace for that.

I hope this helps!
