How to assign a file to a user in GS using Swagger UI

What we want to achieve: 

Before

After

In order to change the user assignment a POST call should be made to 

/api/projectserver/v2/projects/{projectId}/changeassignment

In the body of the call we need to send additional information about the LanguageFileId, PhaseId, Assigned Users.

How to get the PhaseId and Assigned Users parameters

• PhaseId can be retrieved by making a call to
  

  /api/projectserver/v2/phases/{projectId}

• In order to get the name of the user you want to assign the file you need to make a call to the following endpoint 

  /api/management/v2/users

From the response "UserName" parameter must be used. You can assign the file to multiple users.
