Map location popup content changes

2. Could You advise me which hook/filter I could use for adding the store contact information (phone number) on the map location popup between the shop name and shop description? – https://prnt.sc/sxxzgy
I know that only the files in “views” can be overridden in the child theme by wcfm directory and the map popup content is in the “core > class-wcfmmp-ajax.php” which is not overridable.

Thank You in advance
