getting transcriptions after the toggle was finally set

[LoriF]

HI there, 
I finally researched how to get transcriptions of my meetings. The toggle is now on 🙂 
However, is there a way to get transcriptions of previous meetings, before this setting was turned on? 
There's some juicy important things that I need transcriptions of. 
I hate to try another service IF we can make this happen here. 

Thanks
