could you please add also default entries into the values.yaml file ?

also could you try to add into helper instead of manifest file

Done. I also added them in loki-mixin FYI, because I need it too on my end.

Regarding the default values, I can see they already have {} set in the values.yaml. Feel free to let me know if you would like me to add anything else.

Could you please make a minor change to the charts versions.
And update the changelog: https://github.com/portefaix/portefaix-hub/blob/master/charts/tempo-mixin/Chart.yaml#L53
Thanks.

# -- Additional labels to add to all resources
additionalLabels: {}

# -- Additional annotations to add to all resources
