How to add Autocomplete for the html search field

I am trying to upgrade the project done here How to Add a Map to Your Website Using the TomTom Maps SDK for Web - YouTube by adding the autocomplete.

I would like to see autosuggesting geographical places only.

Please can someone suggest? I am stuck… Do I need to use the SearchBox plugin?

Thank you for any help

Our Autocomplete endpoint doesn’t return geographical places.
