[Star Wars] why did the Jedi counsel not do anything with the information Dooku gave them about the most powerful Sith Lord being the Chancellor?

Seems like information Jedi would do something with. From the movies at least it seems like they did absolutely nothing with that information.

They did. There was a covert Jedi operation to root out the Sith Lord. Mace Windu makes mention of it in the ROTS novel. However, in a brilliant piece of irony, they decided Chancellor Palpatine couldn’t be him because Palpatine pretty much already rules the galaxy.
