Once you install the Claim addon and activate it, a favorite tab is generated at Dashboard >> Listings >> Settings.
In this place, you can activate the claim function. Also, you can add the claim button to the location you want with reference to the code which exists at the Claim Shortcode area.
Basically, once the claim function is activated, a button is added into the author information widget in the single listing page.
The user can compose the claim form by inputting name, email, username, phone number, and contents.
The claim which users compose can be checked at Dashboard >> Claim and be approved through the Approve button.
