Omit Client Secret field for authorization code with pkce

[ArieGato]

Is it possible to hide/omit the client secret field for Authorization Code with PKCE?

I have the following configuration:

        services.AddOpenApiDocument((opt, _) =>
        {
            opt.AddSecurity(appSettings.Jwt.Scheme, [], new OpenApiSecurityScheme
            {
                Type = OpenApiSecuritySchemeType.OAuth2,
                Flows = new OpenApiOAuthFlows
                {
                    AuthorizationCode = new OpenApiOAuthFlow
                    {
                        Scopes = new Dictionary<string, string>
                        {
                            { "https://...", "Access scope ..." }
                        },
                        AuthorizationUrl = "https://...",
                        TokenUrl = "https://..."
                    }
                }
            });

            opt.OperationProcessors.Add(new AspNetCoreOperationSecurityScopeProcessor(appSettings.Jwt.Scheme));
        });

    app.UseSwaggerUi(sett =>
    {
        sett.OAuth2Client = new OAuth2ClientSettings
        {
            ClientId = appSettings.ClientId,
            ClientSecret = "",              // <-- this makes the field empty, otherwise a dummy value is generated
            UsePkceWithAuthorizationCodeGrant = true
        };
    });
