I found the following at the end of https://microsoft.design/articles/introducing-kermit-a-typef...

"The basic styles of Kermit (Regular, Bold, Italic, and Bold Italic) are available today in Office, with the remaining 38 styles arriving in early May."

It's listed here: https://support.microsoft.com/en-us/office/cloud-fonts-in-of...

I didn't find an actual license. The typography faq presumably applies to the cloud fonts: https://learn.microsoft.com/en-us/typography/fonts/font-faq
