How to expose filter for entity reference as dropdown in the Search API view?

In my Search API view, I’d like an Exposed filter > Entity reference to be a select box, not a text field.

Details

I have a view which I created like:

  • Views > Add new view > Show: default node index

So it uses the Search API index as a basis.

In the Search API I have ticked to index field_entity which is an Entity reference > Content_type: entity (confusing naming, I know).

I want the user to go to the views page & be able to filter the view results by field_entity (which is an exposed filter/entity reference).

The issue is the view shows the exposed filter as a text field. I have edited field_entity & checked the box Render Views filters as select list – this works fine for a normal view but not for a Search API view.

Question

Can I somehow convert this text field to a select box?

To clarify, I cannot use custom or contributed modules on this project, so it needs to be done without using hooks, or other modules, etc.
