How to create a user group and assign a Browser only role in SSRS.

I need to create a group that includes users who have no design or edit permissions.

How do I create a group and assign the Browser role to this group?

The Browser role includes permissions that are useful for users who view reports, but do not necessarily write or manage them. This role provides basic capabilities for users who belong to either the Contributor or Reader group in a team project.

Thanks,
