The cipher was just the confirmation of what Imran Khan and his party had already alleged leading up to his removal and subsequent arrest. It was already well established that the USA was invovled via the army, which is why he was charged with several phony cases like illegal marriage and state gift sales.
If you want I can share the timeline of events, but it'll take me some time because said army nuked Pakistani media reporting so I would have to rely on 3rd party archives and crossposts of independent journalists who also got content deleted and arrested.
And I do mean nuked, they straight up banned the use of his name in any new article or broadcast, along with banning twitter and flicking the internet connection every other week to reduce info from social media.
The Wikipedia article has some decent sources, but Geo and Dawn are already considered political propaganda.
