You need to clone this repository, rename the folder to devhub and move it inside the franz dev recipes directory. Then, restart Franz. Try the one-liner below:
$ git clone git@github.com:devhubapp/devhub-franz-recipe.git ~/Library/Application\ Support/Franz/recipes/dev/devhub
$ git clone git@github.com:devhubapp/devhub-franz-recipe.git %appdata%/Franz/recipes/dev/devhub
$ git clone git@github.com:devhubapp/devhub-franz-recipe.git ~/.config/Franz/recipes/dev/devhub
If the above doesn't work, check the official instructions.
