python3-websockets dependency not resolved for RHEL

[orensbruli]

Package rmf_demos_panel depends on python3-websockets and it's not defined what package should resolve this dependence:

Could not resolve rosdep key 'python3-websockets' for distro '8':
No definition of [python3-websockets] for OS [rhel]
	rosdep key : python3-websockets

Failed to resolve python3-websockets on rhel:8 with: Error running generator: Failed to resolve rosdep key 'python3-websockets', aborting.
python3-websockets is depended on by these packages: ['rmf_demos_panel']
<== Failed

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