All the above updates will be installed automatically on consumer devices. You can force the update check by visiting Settings > Update&recovery > Windows Update; there, click on the Check for updates button.

I would like to mention that Windows 10, version 21H1, 20H2, and 2004 share the same code base, and technically they have the same code and files. So that's why the patch number remains unchanged for these versions of the OS. The similar situation is for version 1903 and 1909.
