How to summon a mob with a player head in Minecraft 1.16

I am trying to make an adventure map, and I wanted to summon a zombie with a custom head, like in hypixel. Most of the websites I was on had outdated information. For this example, lets just say I am trying to summon a zombie with Notch’s head.

I was asked to describe previous attempts to make the question clearer. Before we start, I would like everyone to know that I’m pretty much the worst syntaxes.

For research, I looked at this site. https://www.minecraftforum.net/forums/minecraft-java-edition/redstone-discussion-and/2736291-summon-mobs-with-custom-heads

The only problem with it is that it is outdated. (2016-2018) But, despite that I tried making my own command. I think the main problem is that I haved mixed up some of the brackets and such.

/summon zombie ~ ~1 ~ {Silent:1,ArmorItems:[{},{},{},{Count:1,id:minecraft:player_head{SkullOwner:Notch}}]}

The problem I am getting with this is that the command block is telling me I need to add some brackets and curly braces in this pattern }]} after the word minecraft.
