How to access all of my recorded audio tracks in a video file?

When recording gameplay footage with OBS I assign the audio to multiple tracks in order to have access to them individually.

Track - 1 Microphone Audio

Track - 2 Discord

Track - 3 Game Audio

Track - 4 All combined

But when I import the video into PPCC I only get access to the Game Audio. I'm really new to video editing and PPCC, I've been trying to Google a solution for the past month or so, and I've finally decided to join the forums to find the answer. Is there some settings or anything I need to access/change in order to have access to my files? I understand it's not as simple as it would be in Final Cut, but I haven't found any programs that could substitute that kind of work. Please help.
