Refinitiv .NET Library GrantRefreshToken returns unsupported

I am unable to authenticate a PlatformSession using the Refinitiv.Data libraries (v1.0.0-beta2) for .NET when trying to use GrantRefreshToken grant type.
session = PlatformSession.Definition().AppKey(appKey)
.OAuthGrantType(new GrantRefreshToken().UserName(username).RefreshToken(refreshToken))
.TakeSignonControl(true)
.GetSession();
Response when trying to open a session using the above
{PlatformSession (Cloud)}
[Refinitiv.Data.Core.PlatformSessionCore]: {PlatformSession (Cloud)}
LastEventCode: SessionAuthenticationFailed
LastEventMessage: {
"ExceptionType": "System.NotSupportedException",
"Message": "PlatformSession (Cloud) authorization using grant GrantRefreshToken
{\r\n\t\tUser: raymond.tieu@refinitiv.com\r\n\t\tRefresh Token: 914d1286-2bcb-4719-8bd8-c872bf3880ca\r\n\t}
not supported."
}

I have tried passing a refresh token obtained from https://sts.login.cp.thomsonreuters.net/oauth2/v1/token after getting the access/refresh tokens using my username and password.
I am able to authenticate a session when using the GrantPassword grant type. Is the GrantRefreshToken implemented in the .NET libraries?

RDP only supports the password grant authentication mechanism. In the near future, RDP will be supporting Client Credentials which will also support the self-signed client assertion. When these details are finalized, they will be supported within the Refinitiv Data Libraries (Python, TypeScript and .Net).

You stated you found success when using the GrantPassword. Is there a reason you are not using this? What are you trying to achieve by using the GrantRefreshToken?

Currently I am authenticating using the PKCE authorization code flow and obtaining the tokens from AAA to then connect to RDP. I was hoping the .NET library would be able to allow authentication using the token from the AAA server so there would be no need to handle client usernames and passwords.
