Navigation to a URI with UiPath

Hi,

I have a process created which is almost done but I am stuck on the last part.

The process is to open an application and supply it with arguments, using a URI scheme. The scheme looks something like this:

penneo:{“name”:“Test Casefile”,“language”:“en”,“signers”:[{“name”:“Jane Doe”,“ssn”:123456789,“email”:“jane.doe@fakemail.com”}]}

Pasting it into a browser works fine like this:
penneo:browser,%7B%22name%22%3A%22Test%20Casefile%22%2C%22language%22%3A%22en%22%2C%22signers%22%3A%5B%7B%22name%22%3A%22Jane%20Doe%22%2C%22ssn%22%3A123456789%2C%22email%22%3A%22jane.doe%40fakemail.com%22%7D%5D%7D

When I try to navigate to it using the attach browser → Navigate to, I am getting an error and cannot navigate using that activity. I could of course click in the URL box and type it in, but that feels like a bad solution.

Do any of you have a better option than using navigate to? Perhaps triggering it with invoke code or something similar.

Thanks
