Unable to switch to Modern Experience

I'm working on creating a new repository for our team, and I want to be able to copy and reuse folders in the folder structure. Apparently, I can only accomplish this in the Modern Experience. Okay, great. https://support.microsoft.com/en-us/office/switch-the-default-experience-for-lists-and-libraries-from-new-or-classic-66dac24b-4177-4775-bf50-3d267318caa9 At a previous job, there was a link in the bottom left that allowed one to toggle, but that's not there. The place the instructions say to change the setting doesn't exist. The "List Experience" section isn't there. This is what my Advanced Settings for a library looks like:

I am not the highest up admin, so perhaps it's something I have no control over? Is it in some other location in whatever crazy version of SP I have?

Thanks in advance!
