Adding intersecting information from point layer to polygon layer pop-up window in ArcGIS Online using Arcade

I have two layers. One point layer and one polygon layer.

The point layer has several points that fall within each polygon. The points represent different types of sports, and the polygons represent the buildings that house these sports.

I want to be able to click on a building, and have a pop-up which lists all the available sports within that building. I am using Arcade expressions in the pop-up, but am stuck on only being able to list one of the sports on the pop-up using this tip:

Is there a way to list all of the sports that intersect?
