I think there must be an error with this API (the way it's mapped through the library)? I see how mmcli grabs the message data with mm_sms_get_data(), but I don't see how the [python] interface - e.g. https://lazka.github.io/pgi-docs/ModemManager-1.0/classes/Sms.html#ModemManager.Sms.get_data - can be correct/usable?
