How to use autocomplete widget in StreamField?

[egegunes]

Hi, I'm trying to use this package to have an autocomplete widget in blocks of a StreamField. I realized I can't use AutocompletePanel inside the StreamField and tried my luck to use Autocomplete widget inside the block but couldn't resolve the issues with telepath, especially UnpackableTypeError on the widget.

Is it possible to use this package to achieve what I want? If not, I'm willing to implement this feature.
