Android Question supabase connection

[kgf]

Hi
I am trying out the supabase library for a mainly offline data app,

    xSupabase.Initialize(SUPABASE_URL,SUPABASE_KEY)
    xSupabase.InitializeEvents(Me,"Supabase")
    xSupabase.LogEvents = True

I would like to check the connection is valid before I show a login screen.
does anyone have any sugegstions,

Thanks
