Save google maps location when creating a meeting for an account

Hey everyone,
When a meeting which related to an account is saving, I want to save the location of this meeting automatically in the database.
In fact, I want the user to create “the meeting” immediately after holding the meeting, and at the same time, the location of the meeting is automatically saved in the system, to make sure that the user is physically present at the meeting place.

How can I do this?
Any better suggestions are welcome.

Thank you to help me.
