Hi Helen,
You can register with the courts online and upload your file(s) there, and they'll get round to it in due course. I uploaded evidence only in September 2023 this way, and it was read and listened too by the judge in December 2023, so that may help give you a bit of an idea of the timescale, however I can't confirm whether it's the same for everyone.
Chris.
