Quarkus vault extension does not support IAM authentication

[sunildparte]

I am using Quarkus to build one microservice at my current job. We use Hashicorp vault and only approved way of authenticating to vault is IAM authentication. Currently there is no support for this in Quarkus vault extension - #11117.
Is there any way around this? Is it possible to write custom credential provider and use it for authentication? How would I achieve that? Any help on this is appreciated.
