Poco X6 Pro 5G Does Not Show WhatsApp Calls on Lock Screen Making It Hard to Answer

I just started using the Poco X6 Pro 5G, but I keep running into a problem with WhatsApp calls. When I get a video or voice call on WhatsApp, the lock screen doesn’t show the incoming call, and my phone just rings. I have to unlock my screen and go through the app just to find out who's calling and to pick up the call. Even after giving all the needed permissions on the phone and WhatsApp, the issue is still there. It's really annoying and takes a lot of time to handle this every time I get a call. I thought this device would offer a better user experience given its quality and price. I really hope Poco sorts this out quickly because it really affects how usable the phone is.
