Customize default visual graphic for Power App visual in Power BI

[TheFlowHawk]

When embedding an app in Power BI as a visual, there is an unsightly load page on the published report that says "How to get started" with steps to connect an app as a visual. The visual then begins to load and the graphic is replaced with the actual app. The ability to disable this graphic so as not to confuse the users so much would be helpful.
