Insert lead in zoho using api v2

Insert lead in zoho using api v2

I'm using the c# sdk in order to insert a "lead" in Zoho.  So far I've been able to generate grant, refresh and access token.  My problem is that the c# sdk documentation stop there.  How can I insert a lead from the v2 API?

This is what I have so far :

//Generate from refresh token
            ZCRMRestClient.Initialize();
            ZohoOAuthClient client = ZohoOAuthClient.GetInstance();
            string refreshToken = "1000.xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
            string userMailId = "x.x@x.com";
            ZohoOAuthTokens tokens2 = client.GenerateAccessTokenFromRefreshToken(refreshToken, userMailId);


            APIResponse leadmodule = ZCRMRestClient.GetInstance().GetModule("Leads");
            
//What do i need to call from here to insert a lead in zoho?

Thank you
