Where can i turn on in my settings the location to be able to view the map after a workout?

Where can i turn on in the settings of my iphone or apple watch 2 to change the settings to always allow location for workouts I’ve tried changing it in my apple watch but it’s greyed out it wants me to go to my iphone <settings >privacy > location services > apple watch workout > while using. I’ve tried doing that but the apple watch worker doesn’t pop up in my settings i’m not sure why I used to be able to see the maps after a workout but i recently reset the factory settings on my xr because of screen issues (still didn’t help) and I don’t know how or where to change the setting any advice or help is appreciated thanks!
