Of course, you can use appero quote in your own custom console-style apps.
Allgemeines zur Verwendung von appero quote in der Lightning Sales Console
appero quote can also be fully used from the Lightning Sales Console.
In the Console view, the appero quote editor always opens as a sub-tab. It is not possible to read out the Salesforce Navigation Rules.
The record action "New Quote" as well as the "New" button at the topic list quotes behave the same and both lead to the quote editor.
