Associate Message button to a user profile

The contact form of the provider is not working https://www.shamimsplugins.com/wordpress/contact-us/

Hi guys, i been trying this plugin, i have a petsitter site, https://www.comosifuerayo.com/ and i need implement private messages between petsitters and petowners. I need to put a “Send a Message” or “Contact” button in the user profile https://www.comosifuerayo.com/resume/carolina-qxzm0hrvgx-el-pinar-ciudad-de-la-costa-canelones-department-uruguay/ and when the pet owner clic to send a private message, that message automatic goes to the petsitter inbox. I don’t want that the pet owner select the contact from the user list, this must be automatic. There is a way to perform this in the pro version? If yes i buy it. Thanks for the information.
