Adding Dreame X40 Ultra to Home Assistant

• 

Hi everyone,
Today I managed to add my Dreame X40 Ultra to Home Assistant using the HACS **Dreame Vacuum** integration.
I also installed the **Xiaomi Vacuum Map Card** to access features like the live map.

Almost all the buttons seem to work out of the box without any additional configuration, except for the zone cleaning feature (or perhaps I’m using it incorrectly).
Could someone please clarify the purpose of the two buttons:
**Zone Cleanup** and the **+ (plus) sign**?

My current understanding is:
* **Zone Cleanup**: starts cleaning a specific room or predefined zone.
* **+ (plus)**: allows you to manually add a zone to be cleaned.
Is that correct?

**In any case, when I try to start cleaning using either of these options, I get the following error:**
```
Action xiaomi_miio.vacuum_clean_zone not found.
```
Does anyone know why this error appears and how I can fix it?
Thanks
