AJAX plugin already exists by default in Construct 2 and 3.
When you double-click in one of your layouts a new window will appear for creating new objects.
Inside that new window scroll all the way down to the Web category until you see the AJAX plugin. Or simply use the search tool and search for AJAX. Double-click the AJAX icon or click on the insert button to add AJAX into your project.
If you do not see the AJAX plugin in your attempt to add it into your project, then it simply means that you have already added AJAX into your project already.
Thanks for playing.
