Traefik rule for accessing a special file inside a directory

I need to redirect traefik to to another would this rule look like?

I tried it with the path directory, but had no luck as the wplogin is a file and not a path...i want to acces the file ONLY in a special entrypoint. All other files should be accessible as normal...

anyone an Idea on this?

maybe @Idez? can you help me out with this?
