How to add a Cross Filtering Guide for Stakeholders? Explain Visual filters other visuals in report

Hello, 

I have built a report that will be used by a variety of stakeholders. Most of them don't know about the visual cross filtering features. I want to add a guide in the report to explain that the visual filter each other visuals I am not sure what would be an efficient way to add that to the report. 

P.S : I will explain the cross filtering in a session but It does not reach all the stakeholders adding it to the report will make sure it reaches everyone

Thank you for your help. Much Appreciated.
