Sendgrid and template id

I cannot get it to work either, the mail is sent but the dynamica data is missing in the email itself. I have this code:

            await strapi.plugins['email'].services.email.send({
              to: user.parent_email,
              from: 'hidden',
              template_id: 'd-e0a5b89b0c594f40ad6f1bd98fd58f44',
              dynamic_template_data: {
                firstName: user.first_name,
                password,
              },
            })

Who know how to solve this!?
