If you san it is never ending table - you cannot download entire table, as it is never ending 😄
If the goal is to download entire table, you need to scroll to the bottom until it reaches the very bottom, but i guess 1000s or more as this depends on your one drive/spo logs retention.
So you really need to know how many logs you want to download and then create flow accordingly.
I would explore if i can get these logs in a form of excel/csv somewhere 🙂
