I want to Emulate Android with custom android kernel. e.g Run kernel 5.10. But according to documentation, I need to download Kernel Image and AOSP Android image. So I did that but they shows how can I run it with these arguments:

launch_cvd --noresume 
  -initramfs_path ../path-to-kernel/../out/virtual_device_x86_64/dist/initramfs.img 
  -kernel_path ../path-to-kernel/../out/virtual_device_x86_64/dist/bzImage

But I don't have initramfs.img I downloaded aosp_cf_arm64_only_phone-img-13263448 and extracted that archive but i got these:


So my question is I have Kernel Image but I don't have initramfs.img how can I emulate android with that.
