The toot you are looking for is here: https://qoto.org/@FailForward/105664225207098189
To clarify, I cared for downloading only the public timeline toots of mine, not replies, nor DMs, etc. and wanted it to be done quick and dirty. If you care about all your toots, you probably just want to export everything. In that case use import export function in Preferences and parse the resulting JSON. Easier and more complete.
As for the actual adapted script I used, I uploaded the snippet here: https://git.qoto.org/-/snippets/159
Good luck!

Thanks a lot! I'll chack it out as soon as I have enough time.
