I am using Passolo SDK 2018. How do you configure the CPAIExportOptions filters?

I am working on an export plugin and I would like to present the user with the exports options and I have the following questions.

1)  I see there is a CPAIExportOptions.TokenInFilter method, but how do you configure what is in the filter in using the SDK?

2)  I see in the Passolo UI when using an export plugin you have the options to write

  1.  all strings
  2. or all strings and deleted strings

     How can you configure this using the SDK?

3)  Is there a way to get only deleted strings or string in the Passolo trash bin using the SDK?
