📚 Documentation: Show APIs Not Supported For Client SDK

[ItzNotABug]

💭 Description

For certain APIs like Users & Messaging which are not available on Client SDKs, the note added on documentation is like below which isn't quite accurate -

No endpoint found for this version and platform

Please switch to a newer version or different platform.

The docs. should instead show something like below -

👀 Have you spent some time to check if this issue has been raised before?

• I checked and didn't find similar issue

🏢 Have you read the Code of Conduct?

• I have read the Code of Conduct

Also suggest adding user account deletion as a template function, as it's a common enough basic requirement for any system that has user account signup and management.
