I used a command line tool that I can’t remember the name of and a quick search isn’t bringing up but I’ll edit this comment when I’m at my laptop.

Edit as promised: I used shreddit. I did come across that while searching earlier but the name didn’t ring a bell.

Be warned, if you search for shreddit there is a paid tool of the same name. That is not what I used.

The tool I used allowed me to give it a GDPR download to nuke everything.

I’ve heard good things about Power Delete Suite too.
