How to remove INSendMessageIntent in Shortcuts app?

I’ve implemented an Intent Extension and added support for handling the INSendMessageIntent in the intent handler class. Currently, this intent is automatically visible in the Shortcuts app by default. However, for security reasons (as it involves handling phone numbers), I want to restrict the use of this intent to Siri only and ensure it does not appear in the Shortcuts app. Has anyone encountered this requirement before or knows a way to prevent the intent from appearing in the Shortcuts app, while still keeping it functional via Siri? Looking forward to your suggestions!
