How do I use sops as an External Tool in my IDE?

I'd like to use sops to edit files in my IDE (Intellij), but I'm not sure how best to set it up as an External Tool.

I found these related questions:

• Use vscode as editor for sops
• How to execute External Tool in IntelliJ

IntelliJ IDEA has no support for --wait and cannot be used via the EDITOR environment.

See this issue and the linked duplicates.

External tool will not work. This can be supported by implementing IntelliJ IDEA plug-in that will integrate with the command line tool to transparently encrypt/decrypt the files you are editing.
