  Pipelines at [myorg / myworkspace] workspace:

     46451911407565  | sarek        | https://github.com/nf-core/sarek     | PRIVATE    

To view

$ tw pipelines view -n shared_hello -w myorg/myworkspace 

  Pipeline at [myorg / myworkspace] workspace:

    --------------+--------------------------------------
     ID           | 151019773731768                      
     Name         | shared_hello                         
     Description  | Shared hello world without CE        
     Repository   | https://github.com/nextflow-io/hello 
     Compute env. | (not defined)                        

  Configuration:

     {
       "id" : "26CgNMOZwFjxEKZ4vb2b4y",
       "pipeline" : "https://github.com/nextflow-io/hello",
       "resume" : false,
       "pullLatest" : false,
       "stubRun" : false,
       "dateCreated" : "2022-11-25T08:03:24Z"
     }

To launch them there is no new option, but now is just working when using the name:

$ tw launch -w myorg/myworkspace shared_hello

  Workflow 5W1qYuVRvzmfU7 submitted at [myorg / myworkspace] workspace.

Fixes #278

Guidelines for testing

• Install development version from actions artifacts.
• Create a shared workspace
• Create one shared pipeline without CE
• Create one shared pipeline with CE
• Try to list them from a private workspace
• Try to launch both from a private workspace
