My custom Plugin changes are not applied.

ttani

My environment is Dataiku built on-premise AWS.
I created my custom Plugin from a Python program recipe.
I edited and saved the recipe.json of this Plugin, but when I invoke the Plugin in the flow screen, the changes are not applied.
I then restarted Dataiku and all the changes were applied.

How can I apply the changes to the plugin without restarting Dataiku?
