Feature Request: Deactivation Button on Hike screen

[devansh12b2]

Is your feature request related to a problem? Please describe.
As of now, backend mutation is available to change the duration of the beacon and by setting it to zero leader can terminate the beacon but it's not user-friendly.

Are you working on this? (Yes/No)
Yes
