Thank you for the shared link,
But can you send how to achieve that in Odoo16?

Thanks,

Hi, thank you for the answer, I tried a lot, but nothing is working for me, here is how my files looke like:

custom_module/static/src/xml/kanban_button.xml

<?xml version="1.0" encoding="UTF-8"?>

<templates>
<t t-extend="KanbanView.buttons" t-name="import_hr.button">
<t t-jquery="button" t-operation="after">
<button t-if="widget.modelName =='res.partner'" type="object"
class="btn btn-primary" t-on-click="_OpenWizard">
Import Contacts
</button>
</t>
</t>
</templates>

custom_module/static/src/js/kanban_button.js

odoo.define('import_hr.kanban_button', function(require) {
"use strict";
var KanbanController = require('web.KanbanController');
var KanbanView = require('web.KanbanView');
var viewRegistry = require('web.view_registry');
var KanbanButton = KanbanController.include({
buttons_template: 'import_hr.button',
events: _.extend({}, KanbanController.prototype.events, {
'click .open_wizard_action_kanban': '_OpenWizardKanban',
}),
_OpenWizardKanban: function () {
var self = this;
this.do_action({
type: 'ir.actions.act_window',
res_model: 'test.wizard',
name :'Open Wizard',
view_mode: 'form',
view_type: 'form',
views: [[false, 'form']],
target: 'new',
res_id: false,
});
}
});
var SaleOrderKanbanView = KanbanView.extend({
config: _.extend({}, KanbanView.prototype.config, {
Controller: KanbanButton
}),
});
viewRegistry.add('button_in_kanban', SaleOrderKanbanView);
});

and the custom_module/__manifest__.py

{
'name': 'Import HR',
'version': '1.0',
'category': 'Extra tools',
'depends': ['contacts', 'base', 'mail', 'sale_management'],
'description' : """
description text...
""",
'data': [
'security/ir.model.access.csv',
'views/res_partners_views.xml',
],
'backend': [
'static/src/js/kanban_button.js',
],
'qweb': [
'static/src/xml/kanban_button.xml',
],
'demo': [

],
'installable': True,
'auto_install': False,
'license': 'LGPL-3',
}
