generate JWT for outbound REST API using JavaScript library in less than 1.5s

Summary:

OIC has RESP API connector that expects JWT. As proof of the concept we successfully hardcoded externally generated JWT with expiry date big enough for PoC.

But once we start research how to make JWT generation inside OIC i noticed that few posts in Integration channel claim failed attempts to make JS run in less than 1.5s (OIC constraint for javascript functions)

Have anyone succeeded to build javascript JWT function that runs fast enough for OIC?

If no what alternative solution available to generate JWT tokens in OIC?

"How To Use OIC Integration With Fusion HCM Using JWT Tokens? (Doc ID 2748813.1)" was very helpful to build PoC with JWT outbound REST API, but can't find clean and easy solution to generate JWT inside OIC with low expiry date
