Sharing a folder over browser-url for non-Tailscale users (funnel is not permanent)

hello, i want to share a folder on my tailscale-server. The users should be able to connect to this folder with their internet browsers without installing tailscale.

I want to share this folder for Non-Tailscale Users:

http://IP-ADRESS/Shares/Browse?dir=/mnt/user/racing

I read about funnel but i don´t know how to do it. I tried this:

tailscale funnel -bg 8000

8000 is the port where my app runs.

The non Tailscale users can open the page in a Internet Browser. But if i close the console or after a while, the funnel is gone and the non Tailscale users can´t access my site anymore. How can i make it permanent?

Can you help me?
