Azure App Service deploy version 4 not showing node 20 in runtime stack

I am upgrading my Node.js application to version 20 and have integrated an Azure pipeline for deployment.

In the Azure portal, under Settings > Configuration > General Settings > Stack Settings, I updated the Node.js version to 20. However, in the Azure pipeline, I am using the Azure App Service Deploy task to deploy my back-end. In this task, I am u

nable to find Node.js 20 listed in the runtime stack options.

If I set the Node.js version to 20 in the portal configuration but do not update it in the Azure App Service Deploy task, the runtime stack reverts to Node.js 18 during deployment.
