I want to add a Geomap to my customer's location, not mine

I am adding a Geomap to my customer's location, not mine
How do I change this

You can use the GeoLocation widget. When the form user submits the form, you will get the exact location coordinates of where the form was filled from. Here's a demo form.

Here's a guide on How-to-Add-a-Widget-to-Your-Form.

Hope that helps. Thank you.
