How to send a Zoom invitation through Visual Studio Desktop application

Question

I found the following API code:

Dim token =

   JObject.Parse(System.IO.File.ReadAllText(ConfigurationManager.AppSettings("TokenFilePath")))

'Dim client = New RestClient($"https://api.zoom.us/v2/users/me")

Dim client = New RestClient("https://api.zoom.us/v2/users? 

status=active&page_size=30&page_number=1")

Dim request = New RestRequest(Method.[GET])

request.AddHeader("content-type", "application/json")

request.AddHeader("authorization", $"Bearer {token("access_token").ToString()}")

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls Or 

SecurityProtocolType.Tls11 Or SecurityProtocolType.Tls12

Dim respons As IRestResponse = client.Execute(request)

'Response.Cookies.Add(respons.Cookies)

Dim dta = String.Format(ConfigurationManager.AppSettings("AuthJwtUrl"), 

ConfigurationManager.AppSettings("ClientId"), ConfigurationManager.AppSettings("RedirectUrl"))

Response.Redirect(dta)

However, Visual Studio is generating errors when using this code.

What is the correct code to use when one wants to send Zoom invitations through Visual Studio?

Thank you
