Resetting an autocomplete dropdown?

In one of our filters panels, we have a dropdown that is optional and acts as an autocomplete dropdown. Essentially the values appear when a user clicks/searches the field. We need to allow the user to reset the dropdown as it's optional if they have added the value and wish to remove it.

If this was not an autocomplete dropdown, then it would be possible to have the default dropdown name as the reset option. However, because it is, this may seem strange. Do you have any suggestions for how one must approach this? These are the things that I thought of: 1. Having none as an option. 2. Allowing them to reset it by removing any value them put in by backspacing it (as the dropdown is autocompleted this is allowed) by clicking out of it - not sure if this is feasible technically yet, but an idea.

An extra piece of context - when this dropdown has a value, another dropdown appears that is connected to it. When the value is removed, that dropdown disappears.

Thanks all!
