Field Relationship with another Post

I’m developing an event site.
I created the “Events” post type and the “Location” post type.
In Location I have a field for the address I would like to show on the dynamic page of events (created with Elementor). I therefore created a field in Events where the user can choose between the existing Locations.
I would like to show in Event (frontend) the location address (not the title) when a user select a place from that field.
I have tried in several ways but I have not succeeded in my intent.
Could you help me please?
