@leonardola I'm not sure if I implemented the filter correctly. When I use the filter in the Storefront theme, I still see 'Payments' in the main admin navigation menu. Before spending more time on testing, I wanted to check in with you first to see if you have any insights or suggestions.
Thanks in advance for your help!

Thanks for working on this issue @BurakParsAydin I left a comment about WooPay getting disabled even when nothing is hooking to the disable_woopay filter
