how to see resources logged in with "Dynamics 365 for Tablets" in Schedule Board's "Map View"

Good morning,

in my CRM Schedule Board (Field Service > Resource Scheduling), in Map View, I want to see the GPS position of my Resources.

My resources use the "Dynamics 365 for Tablets" mobile app (not "Field Service - Dynamics 365" mobile app).

Is this possible?

Note that, in Resource Scheduling > Administration > Schedule Parameters, the field "Connect to Maps" is configured to "Yes".

In mobile app, resources have all permissions (positions, ...)
