Remote Scrum exercises

In normal circumstances we would onboard a client to Scrum through a workshop with exercises using Lego to demonstrate the common pitfalls of a bad Product Owner (based off the Lego4Scrum exercises).

With the current situation we're not able to do this but are still keen to run some workshops with clients. 

Does anyone have any suggestions for exercises that can work remotely? If I come up with anything myself I'll also post here.

Thanks!
