Hi,

you can use the JS code below and include it in your custom module. Once installed, it will automatically refresh the Kanban view whenever new tickets are created.

JS CODE:

/** @odoo-module **/

import { KanbanController } from "@web/views/kanban/kanban_controller";

import { patch } from "@web/core/utils/patch";

import { useService } from "@web/core/utils/hooks";

import { onMounted, onWillUnmount } from "@odoo/owl";

patch(KanbanController.prototype, {

    name: "help_desk_increment_refresh",

    setup() {

        super.setup?.(...arguments);

        if (this.props.resModel !== "helpdesk.ticket") return;

        const orm = useService("orm");

        const action = useService("action");

        let previousCount = null;

        let interval = null;

        onMounted(() => {

            interval = setInterval(async () => {

                const count = await orm.searchCount("helpdesk.ticket", []);

                // Only refresh if previousCount is set and count increased

                if (previousCount !== null && count > previousCount) {

                    await action.doAction({ type: "ir.actions.client", tag: "reload" }, { replaceLastAction: true });

                }

                previousCount = count;

            }, 5000); // check every 5 seconds

        });

        onWillUnmount(() => clearInterval(interval));

    },

});

Hope it helps.
