Integrate autosuggest in a form

My problem is: I am using Forminator and Echo KB plugins on a WordPress sites, with other plugins too. I have a form made with Forminator, but the first questions of this form are about entering data (occupations) coming from the knowledge base. However, both do not communicate between themselves, so at the moment, there is a search bar from the KB as a widget on the right side of the website, and the users need to enter their search there, then copy and paste in the text field of the form once they have found what they want. This process is clearly not the best, so I would like instead that suggestions appear in a search bar within the form as they type, and they just click on the response to select it. Just like autocomplete on some websites, except that the KB would provide the data. The KB plugin already has an advanced search feature which allows that, on the main page of the KB. But of course, when you click on the search result, it displays the page. I don't need that, just to select the answer, then the rest of the form is filled normally. One more thing, if possible I would like the search to be limited to one category.
