<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
     <type name="Magento\Backend\Block\Widget\Button\Toolbar">
        <plugin name="AddButtonInOrder" type="MagePsycho\Customshipping\Plugin\Adminhtml\AddButtonInOrder" />
     </type>
</config>

Step.2 Add AddButtonInOrder.php

    public function beforePushButtons(
        \Magento\Backend\Block\Widget\Button\Toolbar\Interceptor $subject,
        \Magento\Framework\View\Element\AbstractBlock $context,
        \Magento\Backend\Block\Widget\Button\ButtonList $buttonList
    )
    {
        if ($context->getRequest()->getFullActionName() == 'sales_order_view') {
            
            $order_id = $context->getRequest()->getParam('order_id');
                $url = $context->getUrl('sales/*/email', ['pickup_ready'=> 'pickup_ready']);
                $buttonList->add(
                    'pickupReady',
                    ['label' => __('Pickup Ready'), 'onclick' => 'deleteConfirm(\'' . __(
                        'Are you sure you want to send a "Ready for Collection" email to customer?'
