- I am testing first with a less relevant add-on on my side
In the new Editor under Deploy > Manage deployments
- It would only show the Library entry with "No active deployment" under Active left section, neither Deployment ID in the main section
- First, click the pencil to Edit the current version (this will not create a new version yet), enter any description there
- Then click Deploy just enable the option create a new version
- Go back to Deploy > Manage deployments and click the pencil Edit
- Click on the version list and select New version, then enter the corresponding new Description and click Deploy [add-on] the new version
- Then go to the GCP console as you do from the legacy Editor to enter the new add-on script version number and Save
