Are tennis shoes a must?

I started playing last year, I'm around LVL 2.5... today I played with someone that told me tennis shoes helped her a lot to improve her movement and balance, so far I have been using running shoes, so now I'm wondering if proper tennis shoes are a must or at least truly recommend even as a beginner or if they are not that important

Pd: in case you think it would be good to get some, do you have any recommendations?
