Why do people say Palestinians are denied equality in Israel?

I’ve been trying to find legitimate examples out of curiosity to see what everyone is ranting about but yet all I find are labels being thrown around like apartheid and oppression but yet I can’t find any examples given along with it. In all honesty, what rights exactly do they not have? I’m genuinely asking just for education and knowledge but it seems like it’s impossible to find examples listed anywhere, and the ones I have found aren’t even true so I just don’t get what rights they’re denied if any. I figured I’d ask on here in case anyone lives in Israel and can provide real information unlike every website that pops up on Google listing vague accusations that can’t be backed up.
