Chirpstack intégration with thingsboard

I am new to chirpstack and I’ve working on a project where I am collecting data from end devices ,sending it to chirpstack and visualising it on thingsboard.
My question is: Is there a gateway bridge between Chripstack and Thingsboard, so instead of creating a device on thingsboard for each corresponding device on chirpstack and using the token to connect them is there a way to connect the chirpstack devices to a bridge gateway that communicate with thingsboard using one only token so the the thingsboard creates automatically all the devices from chirpstack that are sending their data through that gateway?

Try installing tb gateway and change mqtt.json file as per your requirement.
you can find more info here.
also don’t forget to add gateway to you’re dashboard.
