If I may offer an unsolicited suggestion, consider learning how to create a child theme without relying upon a configurator. It’s not all that complicated. The biggest and really the only challenge is locating the enqueued style tag used by the parent theme.

I get that you’re busy and under stress right now with school obligations, so if you do not wish to do this, that’s fine, no problem. At least consider doing so in the near future at a better time.
