Weweb application whitelisting internal application IP

I built an application in Weweb where people can log in with username and password.

I want to restrict their login by whitelisting a specific IP for each user.

After searching online, the only reference that I can find is for Weweb users whitelisting IPs to log in to Weweb.

This is not what I want to achieve; instead, I want to add functionality to my app that will prevent a user from logging in from a different IP address. I am using the Xano database, if this is relevant.

Does anyone have any guides that can point me in the right direction?
