I honestly don't follow any logic here.
Please read this piece. It's legal, but sums up the issues you seem to be batting around pretty well.
Did President Trump Commit the Federal Crime of Bribery?
TLDR...
"To the extent Trump solicited an announcement unrelated to any actual investigation, he was not soliciting an official act that may be described as part of “logrolling.” Trump thus went beyond the exchange of public acts that constitute political or diplomatic logrolling.
His conduct would support a finding of an exchange of official acts (by Trump) for things of value (the public statement sought from Zelensky) and as no public justification for seeking the statement has been offered, the corrupt intent necessary to maintain a bribery charge. "
