I find the action events to load the autocomplete list but I spend some time to find the action events to click or select it but not luck, it seems elusive to me no wonder these thing is powered by Google.
To show up the autocomplete suggestion list, you can use this Action Events in the Advance tab,
You can see it in the attached agent.
Fortunately, you can do the alternative. The site has API link for all search results by country, in this sample, https://www.scania.com/api/dl/dealers?country-code=DE is a result from Germany. I am puzzled why the code is DE. But because there are only 2 letters required for the country, you can generate a 676 API URL based on the 26 letters of the alphabet.
