This stages writes data from the current context to the current pending user. If no user is pending, a new one is created.
Newly created users can be created as inactive and can be assigned to a selected group.
Starting with authentik 2022.5, users can be added to dynamic groups. To do so, simply set
groups in the flow plan context before this stage is run, for example
from authentik.core.models import Group
group, _ = Group.objects.get_or_create(name="some-group")
# ["groups"] *must* be set to an array of Group objects, names alone are not enough.
request.context["flow_plan"].context["groups"] = [group]
