Edit description of Workflows and Workflow-Groups

Hy!

I use KNIME Analytics Plattform 5.2 and would like to edit the description of a workflow-group. In Version 4 I used the description as a changelog. Now I can not open the description of worflow groups. For workflows, it is possible to show the description, but it is not possible to edit it (I use the Classic UC)

Any help is appreciated.
