The Procedural Macros docs does not mention how to create an unsafe attribute

I'm migrating my code to 2024 edition and one of my proc_macro_attribute generate an unsafe attribute. I do like to make my attribute unsafe but can't find any information how to do this in https://doc.rust-lang.org/reference/procedural-macros.html.

That is not possible with a proc-macro. Only the 3 built-in attributes that are currently unsafe can do that.
