About Suse Linux Kernel versions

Actually, My OS version is Suse Linux 15 sp2 and the Linux version is 5.3.18-22-default
I want repositories of this Suse Linux 15 sp2 because I want to install kernel module for this version.
I have tried some commands ( zypper -n install kernel-default-devel-5.3.18-22) to install the kernel module for this version so please provide me any solution for that
