App keeps asking for Sign-In when browsing links from different tenants

[iBusinessBI]

I've built an App that has links to embedded reports from different tenants.

Each time a user clicks on a link from different tenant this message pops up (the user has permissions as an external user).

A simple click on "Sign-In" shows the report immediately, it doesn't require a password, but it is still annoying.

The message pops up even if this user clicked on Sign-In a minute ago.

Is there a way not to pop up this message?

I got around this using the SharePoint Embed URL.  Asks you once, then never again.

@RyonWhy Thank, I've tried Sharepoint Embed, but it even doesn't ask me to sign-in, just shows "power bi icon" and nothing happens.

Did your app also had links to different tenants with external users?

We recently ran into an issue where it's only showing the Power BI Icon for certain users in our org, as if it's still loading. 

If you try to access the SharePoint embed URL directly, it only shows the icon, it has to be 'embedded' for lack of a better term. Usually throwing it into the Power BI tile in Power Apps works fine (again, see issue above we ran into lately).
