Old reports in Zoom Account

Hi,

Please, I have 4 questions:

1 & 2. I used to have a pay account with the reports option, I have cancel the plan recently.

Why I don't have access to theses reports if they were generated when I was paying the account? If I pay again, will I see them back in my account?

3. Is it possible to retrieve reports before the 12 months in any Zoom's backup? Please, I need to prove that people where on that meeting in January 2022.

4. Can reports been download it in a format that isn't modifiable?

Thanks in advance!
