Stuck on Options page

I am using Teamviewer to access a Raspberry Pi in France that I cannot get to due to Covid. I opened the "Options" page to make some adjustments. The page is overscanning, so the "X" that I need to click on to close it is out of the top of the frame. None of the scaling options help. There is an option in "Actions" to send Crtl-Alt-Del, that might help but it is greyed out. Does anyone have any suggestions to help.

Thanks
