Can I pay a portion of my rent using the business account?

I was reading about the home office deduction & got confused: https://www.irs.gov/businesses/small-businesses-self-employed/home-office-deduction.

 

What does it mean that our home office rent is tax-deductible as a business expense? Does it mean that we pay the full rent using our personal bank account then take the home office space rent as a deduction on our personal income? Or does it mean that we’re allowed to pay a portion of the rent using our business account (depending on home office %)?

 

I would assume it's the latter because why wouldn't the IRS let you pay for a business expense using funds from the business.
