Seems to be impossible bt it’s worth adding it to the idea forum.
A possible workaround would be to call a microflow that is limited to certain userroles. This microflow can open a page with a redirect.
It is not possible to do with external pages as you can not call show-page actions in microflows with a defined url.
There might be a rather complicated work around:
you might need to replace the navigation widget with containers and buttons that you have to style to look like a navigation, the buttons call microflows or pages and maybe you can use a java action in a microflow to open the external page. a lot of maybes and a cumbersome approach
Thanks for replies
I’d prefer not to mess with the navigation widget as we have lots of roles and it’s very easy to manage.
