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
