T mobile mesh access points

I connected all my T-Mobile access mesh points into the T-Mobile 5G gateway router with an ethernet cable until all points communicated (turned solid green). I unplugged the ethernet cable and scattered mesh points throughout house, plugged them into power source and all mesh points turned solid green again to indicate communication with the gateway, I assume, but on the T-Mobile Life app I do not see that the mesh points are connected or communicating with the gateway? How do I get the mesh points showing up on the T-Mobile app gateway graphic as connected and show signal strength? Thank You
