Can I use 2 ChatGPT Business seats on the same device at the same time?

I'm the owner of a Business workspace shared with 3 friends — we split the cost because $100/month solo is steep. Now I'm wondering: can I invite a second account of my own to the workspace, so I can use 2 on the same device: web app and codex. Has anyone actually done this? Did it cause any issues?
