Currently node.js versions selectable are 18, 20, 22 and latest available.
Please add 23 as an option. Currently the only way to update 23 is by picking latest available, however that will also upgrade earlier versions.
we need to be able to select both 20 and 23 as versions, so that both are updated, but only within their own major version.
The non-LTS versions of Node.js as a separate release are not added to the catalog due to their very short lifecycle.

If the "Latest" option doesn't meet your needs, then customers can always use Custom Apps as a workaround.
I'm fairly certain that you can't install multiple versions of Node.js on the same device. A newer version will always replace the older version, whether it’s an LTS or non-LTS release.
