Samsung is still updating some of the good lock modules for One UI 7, Lock Star being one of them, which is currently only available in Korea for One UI 7. It should be coming to more regions pretty soon.
Here is the link to the APK for the newest version of LockStar for One UI 7 not everything is working correctly yet but most of it is I have installed it on my S25 Ultra once you install it you will now be able to access LockStar from Lock Screen Settings
It honestly depends on what device you have, & the features of the device. You should be able to go into the galaxy store & search for " good lock " & you can download all the plugins from that app itself.
