In Odoo 15, is it possible to post a message to the product page of the product listed in product_id for an MO, from an an automated action with model of mrp.production?

I tried:
record.product_id.message_post(body=message, message_type='comment', subtype_xmlid='mail.mt_comment')   

This posted a message in the chatter of the product but only if you click through from the MO (which shows the abbreviated version of the product page).  It does not post a message on the actual product page. 

Thanks, -=Will
