ArcGIS Online Basic Viewer - Is it possible to show/include the "Show Related Records" buttom in the WebMapApplication

[MarkoEinspieler1]

Dear all,

I have a question regarding the ArcGIS Online Basic Viewer. I authored a webmap that includes related tables. When I open the pop-up window in the map viewer, I can show the relate data in a seperate table (see screenshot below):

Now, I would like to include this functionality in the Basic Viewer. Is that possible/included out of the box? Because it is not available, when I open the pop-up in the Basic Viewer... (see screenshot below):

Thanks and warm regards,

Marko
