Custom Template with Jupyter not working

im trying to create a custom template that use jupyter, so im referencing the way jupyter installed and start from the official stable diffusion runpod image
https://github.com/runpod/containers/blob/main/official-templates/stable-diffusion-webui/Dockerfile
https://github.com/runpod/containers/blob/main/container-template/start.sh
and the result is the jupyter did started, but when i click the Connect button and "Connect to HTTP port 8888" button, it leads me to a login page of the jupyter notebook
i noticed that the "connect to jupyter" button for the official sd runpod will lead to jupyter notebook link with token as its params (ie xxxx-8888.proxy.runpod.net/lab?token=xxxxx), but with the runpod that runs my custom image, the button only lead to xxxx-8888.proxy.runpod.net
do anyone know how to solve this?
