It's not at all clear that the "Share my location" button is a button

### Steps to reproduce

1. Select "location" from the (+) button on the composer.
2. A popup card shows you the map with your location indicated with a (massive) pin-inside-a-pin. (sidenote: this feels way too big, and hides way too much surrounding map data; for instance, right now I can't even read the name of the street i'm on because the huge circle covers it. it feels like we have visibility-impaired mode enabled)
3. Look around for a button to press to share your location.
4. Notice there's a "Share my location" text at the bottom of the card. It looks a bit like a legend describing what the big pin means.
5. Look around some more
6. Realise that this text is actually a button you're meant to press in order to perform the share.

### Outcome

#### What did you expect?

I expected there to be some hint that the "Share this location" text at the bottom is actually a button you're meant to interact with, rather than a legend or some other informative text:


That could be via a green 'action' highlight of some kind, or making it look like a button (by putting it on a lozenge or whatever), or some other affordance. But right now there ain't no affordance.

#### What happened instead?

This is the 3rd time or so i've tried to share my location, and found myself flummoxed by the UI.
