yellow 20. Lets now print out just the release name..
#gcloud deploy releases list --delivery-pipeline app02 --filter renderState=SUCCEEDED  # --format 'multi(targetRenders.canary.renderingState)'
# gcloud deploy releases list --delivery-pipeline "$PIPELINE" --filter renderState=SUCCEEDED \
#    --format="value(name.split.7)"

# this gets the last release, eg 'projects/cicd-platinum-test001/locations/europe-west1/deliveryPipelines/app02/releases/app02-20220603-1621'
# then gcloud tokenizes it into semicolons, ive tried hard to do name.split()[7] but didnt work and couldnt find gcloud documentation on other functions like split.
