Updating OIDC connection "show_as_button" using Management API client

I’m trying to update the show_as_button flag of an OIDC connection through the management API, it works using Postman, but I can’t find how to do it using the Management API client.
I’m using the Management API client 7.11.0 in a .Net Framework application.
The ConnectionUpdateRequest class does not provide a field for this flag, and neither putting it in the Options or Metadata dynamic objects works.

Is this not supported by the .Net client?

Thanks

I’m hitting the same problem in the java client
