I don't see your explanation… that note just tells you you can ssh via GSM into the module if your data plan supports it, which has btw been done successfully
by some users and is considered useful.

If you have correctly put your public key into the config store as documented, maybe you've missed the cipher deprecation issue.
You need to add a host entry to your ~/.ssh/config like this:

> cat ~/.ssh/config
Host dexze85.local
Ciphers +aes128-cbc
