Hello

Odoo web architecture has written to display systray activites dynamically. please have a look following method and base javascript.

No need to create customized activity to display it on systray dropdown. you just need to create activity for your new model(object) and system will automatically fetch and display icon of that purticular app's icon where that obejct or model defined. you can see in below screenshot if we create activity for pos order it's automatically display pos main menu icon with activity details.

just create your activity for your custom model and have a look.

@api.model
def systray_get_activities(self):

javascript method to fetch data from python systray_get_activities method.

_getActivityData: function () {
    var self = this;

    return self._rpc({
        model: 'res.users',
        method: 'systray_get_activities',
        args: [],
        kwargs: {context: session.user_context},
    }).then(function (data) {
        self._activities = data;
        self.activityCounter = _.reduce(data, function (total_count, p_data) { return total_count + p_data.total_count || 0; }, 0);
        self.$('.o_notification_counter').text(self.activityCounter);
        self.$el.toggleClass('o_no_notification', !self.activityCounter);
    });
},

Thanks & Regards,
