how to set the camera of a player to another entity?

[cookies]

im trying set a player's camera to another entity. i searched on skhub and found this effect. it seems to be the solution for me, but i dont understand what packets are and how to use them.
here is my code:
command /fakecow:
permission: op
trigger:
spawn fake cow at player for all players with id 23
set camera of player to cow with id 23 for 3 seconds

Because the link I gave said so, packets are everything

command /fakecow:

set camera play_server_camera of player to cow with id 23

it doesnt understand the event.

Because you put the name of the packet instead of just putting “packet” or just nothing

whats the difference between nothing and packet?
also removing "play_server_camera" and replacing it with nothing/"packet" doesnt work, it still gives the same error.

Learn how to read the docs, anything between a [] is optional
