Hi
In the mobile version I don’t think there is a way. You will have to convert in another app and then import.
In the desktop version go to <edit><filters><adjust colour> and set the colour slider to 0%.
That’s about the best I can do. Markw will no doubt be along in a while and can correct me if I’m wrong, which is possible
