*Title*: *validating two tokens in the headers and ignoring one header if not present.*

*Description*:
The requirement I have is to accept and additional token header named `X-originating-api-authorization`, validate it along with the default authorization header using same issuer but ignore the check if `X-originating-api-authorization` is not present.

I have tried to achieve this by using allow_missing: {} but it doesnt work.

Envoy config as follows:
rules:
- match: { prefix: "/" }
requires:
requires_all:
requirements:
- requires_any:
requirements:
- provider_name: xyz_auth_pageSize
- allow_missing: {}
- requires_any:
requirements:
- provider_name: xyz_auth0
- provider_name: xyz_abc_auth0

please help find a solution
