How to include links to Ext JS documentation in JSDuck generator?

Question

ExtJS/Sencha

My classes are inherited from Ext.* classes and I would like to see them in my documentation (so that there are links in inheritance and, most importantly, that the @inheritdoc tag works).
But at the same time, it is necessary that they were not in the class tree on the left. On the left in the tree, I want to see only my packages, classes.
The option "--external": "Ext.*"doesn't help. The Ext.* classes are still included in the class tree on the right.
