I'm trying to open a wizard (form view) in a new browser tab after selecting leads in crm.lead's list view. For that,

In my inherited crm.lead model, I have the following code:

class CrmLead(models.Model):
    _inherit = 'crm.lead'
	​@api.model
   def action_open_analysis_tab(self):
        lead_ids = self.env.context.get('active_ids', [])
        if not lead_ids:
            raise UserError("Please select at least one CRM Opportunity. (crm.lead)")

        base_url = self.env['ir.config_parameter'].sudo().get_param('web.base.url')
        action = self.env.ref('crm_agg.action_groupby_lead_analysis_wizard')

        # Context to pass to the wizard
        context = {"default_lead_ids": lead_ids}
        encoded_context = urllib.parse.quote(json.dumps(context))

        # Build correct URL for act_window
        url = (
            f"{base_url}/web#"
            f"action={action.id}"
            f"&model=crm.groupby.lead.analysis.wizard"
            f"&view_type=form"
            f"&view_mode=form"
            f"&target=new"
            f"&context={encoded_context}"
        )

        return {
            'type': 'ir.actions.act_url',
            'url': url,
            'target': 'new',
        }

server action that calls the above code:

<record id="action_open_analysis_tab_server" model="ir.actions.server">
        <field name="name">Analyze Opportunities (New Tab)</field>
        <field name="model_id" ref="crm.model_crm_lead"/>
        <field name="binding_model_id" ref="crm.model_crm_lead"/>
        <field name="binding_type">action</field>
        <field name="state">code</field>
        <field name="code">action = records.action_open_analysis_tab()</field>
    </record>

(I've tried action = env['crm.lead'].action_open_analysis_tab() as well, but doesn't work)

my groupby wizard:

class GroupByLeadAnalysisWizard(models.TransientModel):
    _name = 'crm.groupby.lead.analysis.wizard'
    _description = 'GroupBy Lead Analysis Wizard'

    lead_ids = fields.Many2many('crm.lead', string="Leads")
	​ # other fields .....
	​
@api.model
    def default_get(self, fields_list):
        res = super().default_get(fields_list)
        lead_ids = self.env.context.get('default_lead_ids')
        if not lead_ids:
            raise UserError("Please select at least one CRM Opportunity. (default_get method)")
        res['lead_ids'] = [(6, 0, lead_ids)]
        return res

The lead_ids are passed in crm.lead's action_open_analysis_tab, but they are not present in crm.groupby.lead.analysis.wizard's default_get.

How can I ensure that the context is passed?
