Missing Warranty Card in Open Box Purchase, Is That a Problem?

So on a whim I picked up a Zephyrus G14 2021 open box for a very good price from my local Best Buy. The laptop looks fine, but I'm noticing that I'm missing the box that apparently includes the manual and warranty card going from unboxing videos of this machine. Is that going to be an issue if I have to send this back in for warranty? It otherwise looks fine past a scare I had when it shut down from a completely drained battery while I was loading windows (I'm not sure it didn't actually just naturally drain down by itself, battery report doesn't show any previous charging or use for the past 5 months), but I was wondering if the inability to send in anything past an online proof of purchase would affect things in the future.

Anyone have any issues with missing that sort of documentation?
