}List the users enrolled in a program
Returns the users that have an enrollment on the program identified by the X-Meridian-Program-Id header, newest first. A user created through POST /v1/auth/users appears here once enrollment has started. Both SINGLE_USER and MULTI_USER integrations may call this endpoint; no X-Meridian-User-Id header is required.
