NoVNC console fails to connect

I have deployed DevStack with two nodes, one node with Keystone, Cinder, Glance, Horizon, Nova and Neutron, and the second node just with Nova compute and Neutron agent services. When deploying an instance I cannot connect to console via NoVNC. Looking into it I found out that DevStack created a multi cells implementation and created nova-novncproxy for cell 1
from systemd service file <email address hidden>
ExecStart = /usr/bin/nova-novncproxy --config-file /etc/nova/nova_cell1.conf --web /opt/stack/noVNC

But nova-consoleauth was created connecting to API MQ, from systemd file <email address hidden>
ExecStart = /usr/bin/nova-consoleauth --config-file /etc/nova/nova.conf

I created another nova-consoleauth connected to cell 1 MQ then I realized in that case the rpcapi of nova-consoleauth was not implemented with routing mechanism to the right MQ for the cell, so I changed nova/consoleauth/rpcapi.py creating an instance of ClientRouter object to be able to route to the right cell MQ when we have multi-cells, and the console access worked, bellow is the diff of stable/queens and the changes I have made

[root@wltpnj22nce-h-pe1dlsc-001 system]# diff /opt/stack/nova/nova/consoleauth/rpcapi.py /opt/stack/nova/nova/consoleauth/rpcapi.py_bkp

I was wondering if such code should be there (also checked Rocky) for the multi-cells use case, or something wrong with Devstack version I used or even I am missing something on console access authorization and console token checking should work.
I have attached the rpcapi.py file I have changed.
