Blocking navigation in webix jet

Hi, I have this code https://snippet.webix.com/i27hlu8g
what I need is to block the navigation in the url.
For example i go from http://localhost:32525/#!/license to http://localhost:32525/#!/user but I need to block the return from http://localhost:32525/#!/user to http://localhost:32525/#!/license.
Is there a way to do this in webix jet? thanks

Hey @Hellekin, sounds like using the UnloadGuard plugin is your best bet in this case. It does exactly what you want - prevents the url change on certain conditions.

Here is an in-depth guide describing the use of the plugin with some examples provided - https://webix.gitbook.io/webix-jet/part-ii-webix-jet-in-details/plugins#unloadguard-plugin.
