How to handle user location on facebook? C # Botframework

I am developing a bot using Microsoft botframe in C #, which will be deployed to messenger.

Enabling the features I'm trying to enable displays points of interest around the users location. I found this curl request on facebooks development site.

curl -X POST -H "Content-Type: application/json" -d '{
  "recipient":{
    "id":"USER_ID"
  },
  "message":{
    "text":"Please share your location:",
    "quick_replies":[
      {
        "content_type":"location",
      }
    ]
  }
}' "https://graph.facebook.com/v2.6/me/messages?access_token=PAGE_ACCESS_TOKEN"

      

        
        
        
      

    

Appart from this I haven't found a way to specify when to send a request for users' location, nor a way to store the location so that I can use it to search nearby.

If anyone could point me in the right direction, I would be very grateful.

Here is a good example of what I am trying to replicate.
