RestSharp upgrade to 108

[E-PressSend]

Hi Guys,

I'm getting an error while running my app which is caused by the fact that another dependency uses the RestSharp v108, while HubSpot.NET uses version 106.

Is there any plan to upgrade this library to RestSharp 108? is that very time consuming?

this is the error I'm getting while using HubSpot.NET:

Microsoft.Azure.WebJobs.Host.FunctionInvocationException: Exception while executing function: CreateTicket
 ---> System.TypeLoadException: Could not load type 'RestSharp.IRestRequest' from assembly 'RestSharp, Version=108.0.1.0, Culture=neutral, PublicKeyToken=598062e77f915f75'.

   at HubSpot.NET.Api.Company.HubSpotCompanyApi.GetByDomain[T](String domain, CompanySearchByDomain options)
...

Cheers
