Oh most of us that change it so often make the icon ourselves.
If anda ever find an image anda want to be an icon I could always make it for you. XD Ive made probably near a thousand atau so icon oleh now. I really enjoy making them
But essentially anda cari up whatever anda want an icon of, anda find an image that anda think would make a good icon, take it to some kind of editting software (or paint if anda dont plan to do much to it), and at the very least, crop the image to be the size anda need it to be (square)
anda can get lebih creative with it the lebih your practice too
I usually used
link to ubah and crop and all cause its like Photoshop but online free and has no downloads. Not as good as Photoshop but definitely plenty enough.
