PLEASE HELP!

So, this weekend I started to potty train my oldest who will be three in May. I know for some it may be a late start but I also have a 1 year old and just didn’t have the time & thought she would see her sister in diapers and forget the whole concept. ANYWAYS, I started! Today was day 1 of training. All day today she’s been with out bottoms (naked). I was expecting accidents or at least attempts to go in the “potty” but not one attempt or accident. I’ve given her plenty to drink just so she would go more often to get the hang of things but NOTHING! I put her on the potty every now and then just to try but again NOTHING! I’m starting to get super frustrated and don’t know what to do? I have a feeling a put anything on her bottom she’ll end up going 🤦🏽‍♀️ Please any and ALL tips/tricks, advice would be very much appreciated. I want to throw the towel in already but don’t want to confuse her.
