Quick access to self-generated doctype

I have a question: when I create a new document type, I can only find it through the search box in the upper right corner. But I want to create an icon for this document type and have it display the modules on the left side of the application. So what can I do to get quick access to it?

You have to create a workspace in that, you can add shortcuts for that particular doctype
