Please use the more robust [publicautocomplete](https://lab.civicrm.org/extensions/publicautocomplete). This is a specific use-case that will be merged into publicautocomplete.

- we want to ensure that it's not easier to create a new organization than it is to choose an existing one, reducing the number of duplicate to a minimum
- it uses the standard select2 widget
