4YO refuses to wear pull up or go potty before bed

Ni

My 4YO daughter recently started refusing to wear a pull up at night and she won’t go potty before bed either. She’s always been a little weird about being told when to go potty and I don’t really blame her bc she was super easy to potty train (literally only had one accident ever) and is good about going when she “needs” to go. We’ve used all the tricks at bedtime (taking away privileges, bribery, making it a game, giving her choices, etc.) to try to get her to go potty or put on a pull up and nothing is working so I’m just gonna buy some waterproof covers for the bed and, I guess, just let her sleep in her undies and let her learn the hard way?? I think she will learn fast that she has to go potty before bed or wear a pull up or else have an accident. Anyone else have any other tips or suggestions??
