Looking good! ❤️
Could you rebase the main branch (there are some merge conflicts) and also add some e2e test for this feature? We already have some e2e tests for Azure Key Vault that you could use as example: https://github.com/kedacore/keda/tree/main/tests/secret-providers
In order to have the KMS, you need to create it through the testing-infrastructure repo (we can help you with that if you want)
Also, this feature requires changes in docs explaining it 🙏

Any update? We aim to cut a release next week

I am really occupied by other things. I don't have plans to do this in coming week.
