Here is a code example you may refer to:

 public void Test()
     {
    
         PlayFabClientAPI.LoginWithCustomID(new LoginWithCustomIDRequest
         {
             CustomId = "test"
         }, re =>
         {
             Debug.Log("LoginSuccess");
    
             PlayFabEconomyAPI.SearchItems(new PlayFab.EconomyModels.SearchItemsRequest
             {
    
             }, result =>
             {
                 Debug.Log(result.ContinuationToken);
    
                 //You may process the Items from the result at here
    
                 SearchItemLoop(result.ContinuationToken);
    
             }, error =>
             {
                 Debug.Log(error.GenerateErrorReport());
             });
    
         }, er =>
         {
             Debug.Log(er.GenerateErrorReport());
         });
            
     }
    
     public void SearchItemLoop(string continuationToken)
     {
         if (continuationToken != null)
         {
             PlayFabEconomyAPI.SearchItems(new PlayFab.EconomyModels.SearchItemsRequest
             {
                 ContinuationToken = continuationToken
             }, result =>
             {
                 Debug.Log(result.ContinuationToken);
    
                 //You may process the Items from the result at here
    
                 SearchItemLoop(result.ContinuationToken);
    
             }, error =>
             {
                 Debug.Log(error.GenerateErrorReport());
             }) ;
         }
         else
         {
             Debug.Log("Finish");
         }
     }
