SliceBuilder gives "[slices API]: Unauthorized error"

Hi,
I'm working on a website right now with nextjs with an existing prismic repository. We want to implement sliceMachine to explore what it has to offer, but we are having a hard time getting it to work.
I used prismic sm --setup --no-prismic then prismic sm --create-slice and it works fine, but when I try to do prismic sm --develop it says [slices API]: Unauthorized
Any suggestions ?

Hi Farhad,

Welcome to the community!

If you would like to try Slice Machine on an existing repository, then we will need to activate it for you. I can do this for you if you provide me with your repo URL, you can send it in a private message if you don't want to share it publically.

Note: The Slice Library feature is not currently available, so it will disappear if you are using it.

Thanks.
