New Taco with CM4?

Hello all!

First time posting here, I have a CM4 and would like to have the Radxa Taco as a lot of the videos I’ve seen online about the Taco worked with CM4s. The product description of the v1.61 states it’s for the CM5 but doesn’t say anything about the CM4 so it’s causing me doubt as to whether it is also supported. Can anyone tell if the CM4 is supported or if I need to purchase the older version (if so where do I get it from)?
