I'm trying to add a third group (in addition to User and Manager) to project app using xml.

<record id="project.group_project_accountant" model="res.groups">
             <field name="name">Accountant</field>
             <field name="category_id" ref="base.module_category_project_management"/>
             <field name="implied_ids" eval="[(4, ref('project.group_project_user'))]"/>
</record>

The group is greated just fine, but in the users group view (Settings->Users->Users->Access Rights->Applications) the selection field for project app is gone...

I have also addes access right for this group using ir.model.access.csv

access_project_project_accountant,project.project accountant,model_project_project,project.group_project_accountant,1,0,0,0

What am I missing / getting wrong?
