Question about "batch_title_player_telemetry_event" function

[AiurTemplar]

Hello guys, I'm still learning this addon and trying batch_title_player_telemetry_event vs write_title_player_playstream_event, these two functions have the same parameters, but when I invoke write_title_player_playstream_event with a callback everything is fine, but invoke batch_title_player_telemetry_event with the same callback, callback function will not be triggered.

Then I'm trying to read the code in the addon which is a little bit difficult for me and I think in "PlayFabEvent.gd", line 98 "batch_title_player_telemetry_event", the "callback" parameter is discarded in the function body, is this the problem? Or am I using the addon in the correct way?

Here is the sceenshot of batch_title_player_telemetry_event :
