How can i make the bottomnavigationbar transparent so that the background is also visible there?

I want to make the bottomnavigationbar transparent so that i can see my background image also as background of the bottomnavigationbar.
How can i do this?

You could try setting the theme variable under Theme (from global toolbar at the top) > Native > $primaryTabBgColor to rgba(0,0,0,0), i.e. black with alpha channel at 0 so fully transparent. If that doesn’t work, then it’s a feature we’ll need to implement – you can open a ticket at https://tracker.appgyver.com

Thank’s for answer.
i have to open a ticket, because this does not work, but the server gives an error on login.
