Hi I have this tutorial module which will help you
https://apps.odoo.com/apps/modules/16.0/d_button_near_create_button/

Hello,

In Odoo we can add buttons near the 'Create' button by extending the view.

For example, if we need to add an 'Upload' button near the 'Create' Button in the Kanban view then extend 'KanbanView.buttons'.

Example

<templates>

    <t t-extend="KanbanView.buttons" t-name="BillsKanbanView.buttons">

        <t t-jquery="button" t-operation="after">

            <button type="button" class="btn btn-secondary  on_upload"  

         name="upload_button">

                Upload

            </button>

        </t>

    </t>

</templates>

if you want to replace the Create button then set the 't-operation' value to 'replace'

<t t-jquery="button" t-operation="replace">

we can also specify the model by adding conditions like

<button t-if="widget.modelName == '<model_name>'">Upload</button>

After adding the button we can create a function in js,
by extending 'web.KanbanController' you can add an action for the newly created button

Example

odoo.define('example.uploadButton', function(require) {
var KanbanController = require('web.KanbanController');
 var KanbanButton = KanbanController.extend({
  buttons_template: '',
   events: _.extend({}, KanbanController.prototype.events, {
       'click .on_upload': '_onUpload',
      },
_onUpload: function(){
// this function will execute  the Button click
}
}

Regards
