Can I drink green tea and mint, lemon balm and chamomile infusions while taking Metformin?

I started taking metformin. I like to drink green tea, mint, lemon balm, chamomile. Are there any contraindications to drinking these herbal teas with metformin? For some time now, I have been drinking green tea every day in the morning, and mint, lemon balm and chamomile in the evening. Depending on what I wanted. Apart from the fact that I like to drink it, it has a lot of health benefits, but I just don't know if you can do it with metformin.
