I wrote custom module to send an email to a sales team when new lead is created like this:

from odoo import models, fields, api

class Lead(models.Model):
    _inherit = 'crm.lead'

    @api.model
    def create(self, vals):
        record = super().create(vals)
        
        template_id = self.env.ref('custom_interface.new_signal').id
        if template_id:
            record.message_post_with_template(template_id)
        return record

And by doing this users from particular sales team get the email with automaticly attached buttons to manage and display the lead.

But I have two companies and two website on different domains. Unfortunetly users sometimes get email from wrong domain (users from Company B get emails with domain for Comapny A).

I think emails with that automatic header and buttons are composed by tamplate "mail.message_notification_email"

And there is a object called "button_access"

How do I make sure that they always get an email with urls from thier corresponding company domain?
