iPhone- will upgrading to Pro access old cloud recordings?

I had a Zoom yesterday, using my iPhone through the Zoom app. A meeting participant started a recording, which I allowed (as the meeting host). Now, I can't find the recording. I understand that I may not have local access to the recording on my phone, and it's not available on the Cloud with my basic account. Is this correct?

If I upgrade to Pro today, will I be able to access an old recording from a day or two before? I have no idea what the record settings were, except that on my desktop the recording location is to my computer. Or might the person who asked to record, who I think also has a basic plan, have access? And is there any way to get this recording without upgrading, which I really can't afford?

This is really important; the session was a memorial service for a young friend who died suddenly while traveling abroad. I organised a group to Zoom with his family from overseas, and we shared stories about the last months of his life that we spent with him. I didn't expect the family to record, so didn't anticipate setting this up ahead of time. Is there anything I can do to sort this?
