[HELP] How import frontend method in a custom panel?

Hello everyone,

I’m working on a custom panel inside a custom_component with custom-card-helpers and lovelace-card-tools.

I would like to create a button that open a config flow dialog from a configEntry id.

I think that the method in the frontend is called showOptionsFlowDialog and located here :

Do you know how can I import this method on my custom panel ?

Thanks a lot, Juicy
