.The Contents pane appears.
Right-click the layer and click Properties
.The Layer Properties dialog box appears.
Click the Display tab.
Click the Display Field drop-down arrow and choose a field.
By default, it is set to the first available string field in the feature layer containing the word
namein the field name.
Tip:
To create a custom display expression, click Set an expression
.On the Expression Builder dialog box, use the Arcade language to concatenate your own text to the text supplied by the designated field, for example, "Street Name: " + $feature.NAME. Custom display expressions use the Feature Display Tile Arcade profile.

Click OK.
