Thank you Jonathan, @JFarmer
For example, we need to change the named version of a map layer's data source to default version.
We create an Addin and OnClick method does the change.
Lets compare two options:
1) The checkbox is not checked
2) The checkbox is checked and the Command ID filled
At the moment, we do not see the difference in behaviour. Meaning
1) user must click the Command's button in order to do the change
2) user must click the Command's button in order to do the change
But our expectation for the second option - piece of Addins C# code executing immediately after the workflow manager step starts, without user click on the Command.
We still try to understand from your explanation, that "run" meaning
1) load (run constructor) on the start
OR
2) make visible the Addin Pane with the Addin
OR
3) whatever ...
Please give an example, for what "Run ArcGIS Pro Command" designed?
