Please try like this.

<record model="res.groups" id="group_scholar_manager">

    <field name="name">admin</field>

    <field name="category_id" ref="module_category_research"/>

<!--        <field name="implied_ids" eval="[(4, ref('group_scholar_user'))]"/>-->

</record>

<record id="group_scholar_spoc" model="res.groups">
