In Odoo 16 CE I'm trying to store the res.company of the current user in the field company_id in a model in my custom module. Whenever the user created a new record of this model, the current company should be stored as well.

The way I'm trying to do this right now is this:
company_id = fields.Many2one('res.company', string="Company", default=lambda self: self.env['res.company'].search(['id', '=', self.env.user.company_id]))

I'm trying to get the res.company record of the corresponding company_id stored in the current user's company_id field. So, I get all the res.company records and search() to get the res.company record where the res_company.id and res_users.company_id match.

Am I approaching this the wrong way? Is there a simpler option? Please let me know.
