How to invoke a NSwag client method that needs bearer token on request header?

I didn't get exactly how NSwag interact with IdentityServerX bearer tokens and adds it request header conventionally? My host api application implements IdentityServer3 with LDAP auth, so as far as i understand; if any host needs to a token for authentication then any client must send it on request header. So how can i deal with it while working NSwag clients ?

Any idea appreciated. Thanks.

I've resolved the issue by using a partial method e.g.

CampaignClient.cs

public partial class CampaignClient
{
    partial void PrepareRequest(HttpClient request, ref string url);

    partial void ProcessResponse(HttpClient request, HttpResponseMessage response);
   
    // Some code...
}

CampaignClient.Extensions.cs - partial class:

public partial class CampaignClient
{
    private readonly IRequestContext _requestContext;
    private readonly IStartupConfiguration _startupConfiguration;

    public CampaignClient(IRequestContext requestContext, IStartupConfiguration startupConfiguration)
    {
        _requestContext = requestContext;
        _startupConfiguration = startupConfiguration;
    }

    partial void PrepareRequest(HttpClient request, ref string url)
    {
        request.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", _requestContext.GetBearerTokenOrTriggerUnauthException());
    }
}

Method override has saved me!
