Proof of funds for french schengen visa, urgent suggestion

I'm sure I am not the only one with this thought, I am going to apply for a French short stay schengen visa from the UK. is it okay if I submit 3 months bank statement containing decent to good cash flow with no certain amount if funds sitting in the account for first 2 months?

My trip is for 3 nights, so, the required funds ain't gonna be that massive as well with accoms and flights being paid for.

Or my bank statements have to show that my funds been sitting there for 3 months with good cash flow on the side? Ik this strengthens the case obviously but it's a desperate moment.
Thanks to anyone who's willing to help me with any sort of information and help.
