Basic `CheckWithLabel` Not working (trying to make a checkbox group)

[CharlestonREM]

Goal: checkbox group with one name and an array of four values

I want to create a checkbox group with one name and an initialValue of an empty array. But it's not working.

docs lacking multiple checkboxes in group example

Docs seem lacking in regard to multiple choices / array. I hope this issue leads to beefing up the docs for future users.

Codesandbox

I attempted to create a checkbox group component with formik-material ui here:
