[lstocchi]

it resolves #121

For better compatibility, I think the parameter should be part of the tool json file.
Now I did not test your stuff but it looks to me that there will be still a dialog be shown and I think this should be hidden or a background task to make sure user does not cancel it.

What if we remove the cancel button from the progressindicator dialog? Atleast the user sees something. Because if we hide everything the user is not aware of what's happening and they see an empty view. If they have a slow connection they don't understand what's going on.
Or we can go with a background task (i guess an indicator is shown on the bottom right side, no?)

TBH having something visible will always lead to user complaining. And user should see a Loading item in the tree, so it's my preference 👍

Now nothing is shown. Only a label (2 processes running in my case as knative is downloading kn and func clis) in the bottom right. If clicked all processes are displayed but not cancellable.

The only issue is that the UI will be frozen because the code is executed in the UI thread and once the background task is launched, the UI thread will be blocked on command.get()
