Unable to make Phoenix Localized Routes work in Phoenix 1.7

I am trying to make this library phoenix_localized_routes/USAGE.md at main · BartOtten/phoenix_localized_routes · GitHub to work in Phoenix 1.7

But it throws errors and the usage section doesn’t correspond with the file structure and content of files in Phoenix 1.7.

Has anybody make this library work with Phoenix 1.7. If so, what did you change to make it work?

UPDATE: The author responded and said that he will look at it, so hopefully it will be possible to use with Phoenix 1.7 soon.
