I would like to ask you is it possible to somehow access all of Siri's history to view it or delete it?
Taken from the privacy file displayed when turning Siri on - off.
You may choose to turn off Siri or Dictation at any time. To turn off Siri, open Settings on your iOS device, tap General, tap Siri, and slide the Siri switch to “off”. To turn off Dictation, open Settings, tap General, tap Keyboard, and slide the Enable Dictation switch to “off”. If you turn off both Siri and Dictation, Apple will delete your User Data, as well as your recent voice input data. Older voice input data that has been disassociated from you may be retained for a period of time to generally improve Siri, Dictation and dictation functionality in other Apple products and services. This voice input data may include audio files and transcripts of what you said, related diagnostic data, such as hardware and operating system specifications and performance statistics, and the approximate location of your device at the time the request was made.
No there is no way to access Siri history. If any of it is stored, it will be stored anonymously as chunks of different words and phrases on Apple’s servers for better voice recognition.
You can delete your Siri data from Apple's servers by disabling Siri in Settings.
Go to General → Siri and disable Siri.
This will delete your history with it. You can enable it again in the future with no problem.
Well, you can't or at least I didn't find any answer. However, if it was questions to ask her on internet, check the Safari history, there will be all your searches through Siri.
