It says it is not a “verbatim” transcript and that it records the notes and recollections of people assigned to listen to the conversation.
So, where is the coverup you claim is happening? Are you saying there’s a verbatim transcript somewhere that the WH refuses to share with congressional oversight? If so, where’s your source, or are you just parroting some anti-Trump rhetoric you heard?
Since you’ve now seen the actual transcript you should try reading it. You’ll see that there was no quid pro quo or bribe or even any pressure to investigate Biden in return for anything.
