Python Plug In file-heif-save

[Julio85]

I´m trying to use that Python PlugIn and it doesn´t work, maybe I´m doing something wrong or introducing wrong parameters.
I need an example to make it work.

I´m using the last version GIMP 2.10.6
pdb.file_heif_save(image, drawable, uri, raw_uri, quality, lossless)

Thanks in advance.
