To find the layerID of a layer in ArcGIS Online that is being used in Pro, one way to do this is to look at the last part of the path when adding the layer, as in the screenshot here:

You might not need to use Arcade though, if you're working in Pro. Pro has select by location. You can select the points that fall within the polygon that way.
