Uncaught TypeError: stepIconContainer is undefined when creating a variant

[szczz]

Hey!

I'm trying to create a custom variant and receive the following error.

I'm adding the variant to the custom theme like this

and here is CustomSteps

If I apply CustomSteps directly to Steps it works perfectly fine. However, I need the variant to prevent the left shift on mobile devices.

Additionally, if I add stepIconContainer:{} directly to the alternate variant, the page renders but the steps have no styles. Do I need to specifically add the baseStyle for this in CustomSteps?

My apologies if this is painfully obvious, this is my first project with Chakra.
