How to read query parameters using custom connector in C#

I have created a custom connector defining the below query parameters. Now, I need to fetch query parameter values and then transform it before sending the request to third-party API. As you can see below, I have defined these parameters under Query section.

Now, I have written the below code in c#, but I am not able to fetch parameter values from JSON object. Now, if I define these parameters in the body section then I am able to fetch it. See below.

private async Task<HttpResponseMessage> TransformRequestAndResponse()

{

HttpResponseMessage response;

var contentAsString = await this.Context.Request.Content.ReadAsStringAsync().ConfigureAwait(false);

var contentAsJson = JObject.Parse(contentAsString);

// Fetch parameter values from the request payload. Below code highlighted in red isn't fetching the parameter values since these values are part of Query parameters.

var formIdvalue = (string)contentAsJson["formID"];

var workspaceIdvalue = (string)contentAsJson["workspaceID"];

var projecttitlevalue = (string)contentAsJson["projectTitle"];

var requesterIdvalue = (string)contentAsJson["requesterID"];

var requesterNamevalue = (string)contentAsJson["requesterName"];

this.Context.Request.Content = CreateJsonContent(contentAsJson.ToString());

// Sending the connector API request

response = await this.Context.SendAsync(this.Context.Request, this.CancellationToken).ConfigureAwait(continueOnCapturedContext: false);

// Manipulate the response data before returning it

var responseContentAsString = await response.Content.ReadAsStringAsync().ConfigureAwait(false);

var responseContentAsJson = JObject.Parse(responseContentAsString);

response.Content = CreateJsonContent(responseContentAsJson.ToString());
