Not sure if my magic mouse is magic mouse 2 or 3

Hello,

I recently bought a magic mouse from a local tech store, brand new.

I want to order a case for it from aliexpress but it seems like the sellers there have multiple types of cases designed for different magic mouse generations 1 2 or 3. For me they all look the same but it is possible to have some differences since the sellers on aliexpress sell 3 types of magic mouse cases.

At the store they said this is a magic mouse 3 2021, but as I have searched online its model number: A1657 I could see various websites which say this is a magic mouse 3 others say it's a magic mouse 2 and it confused me.

On Apple's website it says only magic mouse, but the model number in the picture corresponds to mine: Magic Mouse - White Multi-Touch Surface - Apple

Could you please let me know which generation of magic mouse is this, 2 or 3?

Thank you.
