swupd is not a wrapper of apt-get, so in general you cannot assume it has bundles named same as apt-get packages.

You can try to search them with swupd search, and the query should be the stem of the package name that the prefix, such as lib, and suffix, such as version number, removed.

I know, I was kinda hoping to get them added. Is this the correct way to request missing libs?

For that you should go to GitHub - clearlinux/distribution: Placeholder repository to allow filing of general bugs/issues/etc against the Clear Linux OS for Intel Architecture linux distribution
