One entity to report temperature and humidity to Google Assistant

Hello,

For the moment, I have two sensors: a temperature sensor and an humidity one.
In the Google Home apps, it displays two devices, even if I give them the same name.

Is there a way to have only one sensor which Google Assistant will be able to report the temperature and the Humidity?
For example by adding an attribute with a specific name which will report the humidity.
Or do I have to keep two separate sensors which will display two elements in Google Assistant?
