Magento 2 replace dotmailer/dotmailer-magento2-extension errors with compiler error

Question

We have added the following to composer json in M 2.3.5

    "replace": {
    "dotmailer/dotmailer-magento2-extension": "*",

Then we run php bin/magento setup:di:compile

And are presented with this error

Repositories code generation... 1/8 [===>------------------------]  12% 1 sec 88.5 MiB
PHP Fatal error:  Interface 'Dotdigitalgroup\Email\Block\Adminhtml\EngagementCloudEmbedInterface' 
not found in /var/www/html/m2/m2_dev/vendor/dotmailer/dotmailer-magento2-extension-chat/Block/Adminhtml/StudioChatWidget.php on line 13

Question: Is there more we need to do to disable Dotdigital?

Answer 1

Some additional extensions are bundled with Magento 2.3.5. The error you're getting is to do with the chat client module.

You can remove all modules with the following replaces:

"dotmailer/dotmailer-magento2-extension": "*",
"dotmailer/dotmailer-magento2-extension-package": "*",
"dotmailer/dotmailer-magento2-extension-enterprise": "*",
"dotmailer/dotmailer-magento2-extension-chat": "*",

https://github.com/yireo/magento2-replace-bundled maintains a meta-package that removes third party bundled modules
