Empty embedded content features in dashboard

[AmauryDeLaBretesche]

Hi

Following this post's instructions I would like to display a Feature Layer attribute table in a dashboard.

In my dashboard, I am adding an embedded content referring to a Feature Layer but the result is empty even though the data table contains multiple records (see screenshot). The feature layer is already successfully displayed in the dashboard through a webmap.

My ultimate goal is to select an element on the map and have a the attribute table updated accordingly showing the attributes of the selected element.

Thank you for your help
