python3-flask-socketio not resolved for RHEL

[orensbruli]

Package rmf_demos_bridges depends on python3-flask-socketio and it's not defined what package should resolve this dependence:

Could not resolve rosdep key 'python3-flask-socketio' for distro '8':
No definition of [python3-flask-socketio] for OS [rhel]
	rosdep key : python3-flask-socketio
	OS name    : rhel
	OS version : 8
	Data:
debian:
		- python3-flask-socketio
		ubuntu:
		- python3-flask-socketio
		
Failed to resolve python3-flask-socketio on rhel:8 with: Error running generator: Failed to resolve rosdep key 'python3-flask-socketio', aborting.
python3-flask-socketio is depended on by these packages: ['rmf_demos_bridges']

I need to make further investigation about if this package is distributed or not in fedora and rhel.
