PostMan Custom WebProtocol

I have found that PostMan has browser protocol to open the native app and import a collection:
postman://app/collections/import/631643-dac5eac9-148d-a32e-b76b-3edee9da28f7-JsLs

That’s all opportunities? Maybe I can import collection by url?

Please give me the link to the docs for this feature.

This only works for collections hosted on Postman servers. No plans to extend this protocol yet.
