can i change the login screen SDDM using the lock screen theme on kde ?

I’m new at the community and linux. i recently installed parrot with de kde view. I understand that lock screen and the login screen are different things, but if u can change the login screen theme on kde global configs,¿you could change it for what u want no?
here is the question: i put on the lock screen a video that loops and thats look great ¿can i make it the initial o default display manager?

i tried

sudo dpkg-reconfigure sddm

an put the sddm as default but only have the global theme without the loop video

the extension that i use is “Video Lockscreen” on kde configs
