Three options:
1. Make sure you're using the branded Dynamics Field Service app. This is MS's licensed Resco version and should do what you want.
2. Purchase Resco yourself if you want to customize the mobile app
3. Purchase Maplytics if you want to use the generic Dynamics 365 mobile app but still want mapping on desktop and mobile.
Number 1 is likely your answer, it should do what you see on that screenshot.
