Need to add Directorist listing in Ajax search

Hi, I am having the directorist plugin to display listing information. Now, I want to use the ajax search to perform a search from that listing.

I can not see any default post type has been created to add an Ajax search pro. How can I make the directorist listing searchable from ajax search pro?

Do I have to create any custom field and add to ajax search?

Here is the listing – https://wecruitr.com/all-listings/

I am attaching the screenshot of the directorist listing and ajax search post type. Also, you can use admin login to check the backend.

Thanks,
Unnati
