1.When and where to use this patch

2.patch name use : generate.patch or name-of-file.patch?

[runsiv]

Ah sorry, forgot to put in the location

cd modules/lib/matter <- to change directory where patch need to be applied (matter repository)

git apply <path_to_file>/generate.patch <- apply patch with correct path to downloaded file

Regards

Runar
