Editing tool (toolbar) is missing from whiteboards

I am writing to figure out how to have my meeting attendees access the whiteboard's toolbar. It is visible on the left side of my (host) screen, but after testing with three different groups, no one can access a toolbar. It makes it impossible to collaborate (and I did select that option as opposed to 'presentation' mode). How can participant's see/access the editing tools for the whiteboard???

I have updated my Zoom version and looked in the support/help articles. I found one thread with a similar issue but no specific answer for finding the toolbar (only docking it). Thank you in advance!
