What documents do I need to apply for a DTV visa at the embassy in Paris for self-employment?

Hi everyone ! I'm about to apply for the DTV at the embassy of Paris for the workation / self-employed category for and i have a few questions please :

1) Can i send all the documents in french ? or will they ask documents in english and deny my application if i send everything in french ? Also i've heard about the need certified translations in some embassies, does it also apply to the Paris embassy ?

2) For the bank statement, they ask to show more than 500 000THB for the last 3 months which I have but my bank gave me only one certified and stamped bank statement with written on it the balance date for my savings account i never touched proving that i had the money on the account for way more than 3 months. So it proves it but it's not really bank statements. Do you think it will work for the Paris embassy ?

3) For the address on the bank statement, it shows an old address that i just changed with my bank to make sure everything is updated. Do you think it can cause issues with the approval of my visa ?

4) Since i'm applying for the workation category, just showing one invoice for a client in french+ a proof of bank transfer for this client is enough ? or do i need more than 1 ? (like 5 or 6). Also if there are french here who got approved for this category, do you know if just sending this will be okay for the embassy please : Extrait KBIS in french + 1 invoice in french + 1 cover letter.

Thanks if you can answer me !
