How can we mark a overloaded method obsolete?

Question

I have two functions: Method(A val) and Method(B val), one taking val of type A and the other of type B.

I want to mark Method(A val) obsolete, so that IDE can highlight the fact that it's obsolete.

I have decorated the method with [Obsolete], however, am not seeing it as deprecated.

Am I missing something? From my research, I have only seen examples of creating a brand new method to replace the old one but not seen any example of a overloaded function taking place of the older deprecated one. Any help would be highly appreciated.
