Specify Image tag during (re)deploy

I’m trying to automatically deploy a docker image after CI, by using the API.

Having tested the https://app.koyeb.com/v1/services/{id}/redeploy endpoint a fair amount, I can’t seem to be able to specify a particular image tag to deploy as part of the request.

Is this possible & I’m missing something?

It always seems to deploy the same image tag that I originally specified in the Web UI.
