Teams annotations interact with background

We're having the same issue.... there is no "interact with background" button or menu option. My workaround is this: a) unpin the controls that appear when screen sharing is started. In my case at least, this prevents the screen sharing controls from disappearing when annotations are enabled. b) turn on annotations, c) annotate some stuff, d) when you want to interact with the background, turn off annotations, e) interact with the background, f) when you're done interacting with the background, turn annotations back on. Any annotations that were active when you turned annotations off will re-appear.
