The “Browse” feature is designed for use in the Designer environment, allowing you to test and develop your automation with the package locally. However, due to current limitations in the Runner's ability to download packages directly from Blob storage, the package won't automatically transfer for execution. That's why converting the package to a DLL and using “Invoke DLL” is necessary for now when working with the Runner.
Or you can also checkout the “Robility Marketplace” feature where you will be able to upload and use your customized package in your solutions.
