Here's how you can navigate to a playable's editing page:
- First located the Playable you wish to edit in Playground, click on the name or in any white space along the row of this project
- From here you will see a list of versions (if the project has yet to be edited there will likely be only one version, called "Default Version")
- Click on a version you wish to make changes in
(Alternatively click the Kebab menu (3 dots) along to the right of the version and then select Edit)
- You will be then redirected to the editing page for this version of the playable
