Any tips for a brand new team lead?

So all the details haven’t been told to me yet (I’ll know tomorrow), but I’m being offered a few team lead positions, one is front end which isn’t available right away but will be shortly, and the other is somewhere in GM immediately (idk where in GM though I have a meeting with my coach and the GM coach tomorrow). I have no leadership experience in this kind of setting, so I’m clueless and nervous. I had nightmares about screwing it up last night. Can I get some tips on how to be a good team lead?
