Hi,

In your module you can add a  data file and create team records from code, you can try like this,

<record id="help_desk_team1" model="helpdesk.team">
    <field name="name">Odoo Support</field>
    <field name="alias_name">support</field>
    <field name="stage_ids" eval="False"/>
    <field name="use_sla" eval="True"/>
</record>

Thanks
