title: Google Fit permission
body: <p>I want to show a "connect to fit" button on the main screen, but only if it's not connected yet. </p>
  
  <p>How can I check this, because if I connect my client and it's not approved, the app asked for permissions. Setting a shared pref isn't the solution, because the user can revoke the approval later in the system settings (outside the app).</p>
