Has anyone here worked with WhatsApp business API and location permission like to create a booking system but on WhatsApp with location details?

Hey guys, I am on latest n8n version self-hosted on my raspberry pi using ubuntu server and docker. For SSL I am using Cloudflare tunnel, so i do have https. The problem is when i trying to add google sheets api then in the very last step when the concent has to be forwarded to the redirect url, since n8n is hosted on local, because of this i am unable to authorize, and unable to change redirect url. If i could change redirect url and removed localhost with the https link then it would have worked but it won't allow me to change url, can just copy. I think this problem might be because localhost here mean raspberrypi localhost, and i have accessed rpi ubuntu server from my windows laptop.
