Where to find kernel headers 看全部

I'm very new to linux so please be kind. I'm trying to install Droidcam client on an Opi Zero 2 which I'm hoping will allow me to use an Android phone as a web cam. When I run the install script I get:

Error! Your kernel headers for kernel 5.16.17-sun50iw9 cannot be found.
Please install the linux-headers-5.16.17-sun50iw9 package,
or use the --kernelsourcedir option to tell DKMS where it's located

I've tried finding these on the web but have had no luck. Does anyone know were these can be found or a work around for this issue.
