How to style Google Maps PlaceAutocompleteElement to match existing form inputs?

I’m migrating from the legacy Google Places Autocomplete to the new PlaceAutocompleteElement in my Rails application. The new component is working functionally, but I can’t get it to match the styling of my existing form inputs.
Instead of enhancing my existing street address input field, the PlaceAutocompleteElement renders it as a completely separate input with Google’s default styling, creating an inconsistent UI.

Do you know how to remove the black border and change styles overall in https://developers.google.com/maps/documentation/javascript/examples/place-autocomplete-element#maps_place_autocomplete_element-javascript ?

I can’t find any example with styled widget. I found only for legacy places.
