How to create "go to" links between multiple custom apps


I’ve installed Frappe v14.26 and Frappe Insights v0.3.1
I’ve also created my own custom app named Octopus

Insights does have a “Switch to Desk”, not necessarily to any Octopus objects, but that’s fine.

I’d like to add a similar “go to” link on one particular DocType within Octopus to take the user to Insights at http://octopus-dev1.local:8020/insights/dashboard

I’ve read the Forum but cannot figure out if my requirement is related to links or routes? And how would I achieve this. I’d like to have a simple hyperlink, but even a button will do.

Any ideas? Thanks in advance.
