How to stop baby from crawling away!

My daughter is nearly 10 months and she’s a right little bugger when it comes to changing her nappy 🤣 .. she giggles and crawls off thinking she’s the boss! I’ve tried giving her things to occupy her which isn’t always helpful. She’s standing so sometimes I do it whilst she’s stood up. Other then that what can I do or how can I teach her not to do this? It seems to be hilarious to her haha
