I am new to ArcGIS Online, so also new to Arcade. I am curious how to use the expression builder in AGOL for customizing how my labels appear on the pop up windows. My very basic example shows how my data is showing by default. I'd like to be able to show it as follows:
Name of facility
Address of facility
Phone number of facility
I don't want to show the attribute name either.

Thank you in advance for your feedback.
