How to Bind Custom Text while Add Comment in Admin Sales Order View in Magento 2

 Steps to Bind Custom Text while Add Comment in Admin Sales Order View in Magento 2:

Step 1:  Firstly, we need to create a “di.xml“ file inside our extension at the following path.

app\code\Vendor\Extension\etc\adminhtml\

And then add the code as follows

<?xml version="1.0"?>

<config xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:noNamespaceSchemaLocation='../../../../../lib/internal/Magento/Framework/ObjectManager/etc/config.xsd'>

    <type name='Magento\Sales\Controller\Adminhtml\Order\AddComment'>

        <plugin name='order_add_comment_plugin' type='Vendor\Extension\Plugin\Adminhtml\Order\OrderAddComment' sortOrder='10' disabled='false' />

    </type>

</config>

Step 2:  After that, we need to create an “OrderAddComment.php” file inside our extension at the following path.

app\code\Vendor\Extension\Plugin\Adminhtml\Order

Then add the below code snippet

<?php 

namespace Vendor\Extension\Plugin\Adminhtml\Order;
