Zoom whiteboard

[Juliet45]

Ok so I want to add a background to my Whiteboard that is 'set' and we can sticky note, text box over it without accidently deleting it?  Any help really appreciated otherwise I'm back to Jamboards for functionality???  I regularly like to use slides as background to collaborate over in workshops?  E.g. like a map of the UK and people can sticky note where they are but need the map to stay set?  Many Thanks Juliet
