adafruit io with GCP

I have a project where I need to send data to GCP using Arduino and sim 900 only.
so depending on what I read on the internet that it is not possible to do it directly because the GCP use TLS 1.3 and sim 900 do not support it.
so I had the idea to send that data to adafruit then resend it to GCP.
idk if it is possible could someone help me with it?

I think it was TLS1.2.
In 2G modules, Only SIM800C 32M with a firmware update can support GCP.
You can also write normal Google cloud functions and send data to them by HTTP from SIM900 and they can in turn be coded to forward to IOT core. You can also directly save data to firebase from cloud functions
