Is it possible to have user just provide permission and we can pass location using Directline api request?

[ghost]

We are using Microsoft's web chat on our website.But,we are using Directline api to communicate. I just want to know that is it possible in your project to get user permission for location when our webpage is loaded and then we can pass it with first Directline api request or is it possible only through custom webchat control ?

Basic purpose is to identify each user uniquely.

Any solution?
