Hi,

For many2many fields we cannot enable tracking just like other fields. But you can use message post function for this, which will allow you to post message in to chatter from code

Please refer this link:Odoo Message Post Function || Add Message To Chatter From Code in Odoo
 Thank you

Add tracking for many2many and one2many field in odoo16 is here:

from odoo import fields, Command


field_name = fields.Many2many('comodel_name', tracking=True)


Add the bellow function :

def _mail_track(self, tracked_fields, initial_values):
    changes, tracking_value_ids = super()._mail_track(tracked_fields, initial_values)
    # Many2many tracking
    if len(changes) > len(tracking_value_ids):
        for changed_field in changes:
            if tracked_fields[changed_field]['type'] in ['one2many', 'many2many']:
                field = self.env['ir.model.fields']._get(self._name, changed_field)
                vals = {
                    'field': field.id,
                    'field_desc': field.field_description,
                    'field_type': field.ttype,
                    'tracking_sequence': field.tracking,
                    'old_value_char': ', '.join(initial_values[changed_field].mapped('name')),
                    'new_value_char': ', '.join(self[changed_field].mapped('name')),
                }
                tracking_value_ids.append(Command.create(vals))
    return changes, tracking_value_ids

Thanks!
