I currently have $20k in student loans with paused interest/payments. Pay them off, or invest?

As the title says, I currently have ~$20k in government student loans that have their interest/payment paused. I've continued to make payments on them anyways to get that balance down, but I'm curious what the "best" approach should be. Should I be taking these payments instead and invest them into a HYSA? I'm not sure if that will outweigh getting my payments lower before interest kicks back in. Thanks!

Edit: Loan rates are 6.1% once they eventually resume.
