You CANNOT do what OP describes in Bubble due to how Bubble interprets paths.
(You can’t have myapp.com/handle — because that would be the app page called “handle” with no arguments, right?)
But as others point out, you can have /something/handle.
I’ve described all of this in great detail and built the canonical demo app for it so that no one need ask this again, but I guess perhaps it can’t be found anymore.
