I hope clear my doubts through 2 questions.
1st question - Where can I learn more about pop-ups in arcgis pro but,more advanced ?
The 2nd Question- Related to work. How can I click icons in front of the fields in the table?
and the last one is how can I add a full extand option to the image?
Popup documentation for 2.9
