How to activate "Download" and "upload" buttons in Rasa TopBar

Hello community,

I need to add the “upload” button in order to make it easier to upload a new JSON file

In the rasa-nlu-project, I changed “isOnline” variable with “true” value but nothing changes.

Could you clarify where you’re seeing this (ie in which tool)?

I can upload a file to this link on the Web, but i want this to run locally…

Is this the file that I have to modify ?

This is the 2 buttons déclaration in the code…
