Is it possible to hide my location on FB chat when using my iPhone?

I've just noticed that on Facebook chat for mobile I can look at someone's specific location, I can just click on one of their comments and their location on google maps will show up. Even if the conversation was from a while ago. This is scary as I don't want people to know the exact street address of where I live.
Can this also be shown on Facebook chat when using a computer? Is it possible to make this private?

Just go to Settings>Privacy>Location Services>Facebook or Facebook messenger. From this menu you should be able to toggle location on or off.

Hope this helped
