This is thread about the Durham investigation, not about an information campaign about the Russia investigation (not hoax).
Yes, the Clinton campaign was looking for information against Trump and partly financed the Steele dossier, and also approved leaking information about Alfa Bank servers. This is not illegal.
No, the Durham probe, which aim was to prove that the Russia investigation was not properly predicated, did not succeed.
Facts are:
-the Steele dossier was not at the origin of the Russia probe. Confirmed by the IG investigation and the Durham investigation,
- the Alfa Bank information was given by Sussman after the FBI opened its Russia investigation, it could not have caused it, (from the trial)
- the FBI did not use the information provided by Sussman, as it was not considered as reliable (from the trial)
- the Clinton campaign did not send Sussman (from the trial).
Not only did the Durham investigation fail to prove the Russia probe was not properly predicated, it also indirectly debunked Trumps conspiracy theory! ????

Your last reference was about the GOP-led Senate investigation in 2020. Guess what the conclusion of the GOP-led investigation was?
