Help me to share a whiteboard to just 2 people

In Teams when in video chat with only 1 other person and click Share Content | (there is no Whiteboard app)

❌ Figure: Bad Example – With only 1 other person in the chat there is no whiteboard

When I add someone else to the call I can see the whiteboard app. 

✅ Figure: Good Example – With 2 or more people in a video chat Whiteboard is there

This is weird and wastes a lot of time debugging why this feature comes and goes.  The button should always be there and if Microsoft don’t want to enable it for 2 people for some reason pop a message that says “Whiteboard is for 3 or more users”.
