Custom Object Cryptographic-key lacking in pycti

[R3dHash]

Problem to Solve

Hello, I'm developping a connector for tpotce and as I encountered SSH-RSA let by attackers I wanted to ingest them in Opencti as observables and indicators. I found in the frontend an observable named Cryptographic-key but I could not find it in pycti to populated my bundle stix (I can use the api but I don't want to as all the other objects are created via a bundle stix).

Current Workaround

API works but has drawbacks when we use mostly bundle stix objects

Proposed Solution

Add this custom object to pycti
