Setting up user groups and project configs/permissions

in the Adobe Admin console for the experience cloud I am trying to setup a group of users that I can assign to various projects.  i just need a simple 1 group with read-only access setup.

under "user management" I have created a user group

I have read Manage products and configurations and I think the remaining process is to

1) create a new project configuration,

2) assign the user group to this project configuration

3) set permissions on this project configuration

Problems:

1) when i drop down the "groups" dropbox on a new project configuration, I do not see the group (mcom_students) that I created

2) i do not see any options or tabs to set permissions on project configuration as outlined in this help document Enterprise Help | Manage product permissions and roles in the Admin Console

how does one go about setting permissions for groups and products?

thanks
