Import entities from Alexa

Hi everyone!
I have searched around the community but I still haven’t found the solution for my issue:
is it possible to import entities form Alexa?
In my case I have Legrand Bticino lights, switches and covers, and there is already the integration between Legrand and Alexa. Unfortunately there is still no integration between Legrand Bticino and Home Assistant.

So I’m wondering if I can import entities that are linked to Alexa.
In the logbook I actually see the reporting state of those entities, but they are not present in my entities list under configuration.

Do you know how can I import them?
Thanks for helping.
