Custom methods in a struct is not possible in Julia

[SMMousaviSP]

An example is given that it is possible to have a custom method inside a struct like this:

struct Person
    name::String
    age::Int
    occupation::String
    
    function Person(name::String, age::Int, occupation::String)
        new(name, age, occupation)
    end
    
    function introduce(p::Person)
        println("Hi, my name is $(p.name) and I am a $(p.age)-year-old $(p.occupation).")
    end
end

p1 = Person("Alice", 25, "Software Engineer")
p1.introduce()

However, this code will not run and it should be changed to this:

struct Person
    name::String
    age::Int
    occupation::String
    
    function Person(name::String, age::Int, occupation::String)
        new(name, age, occupation)
    end
end

function introduce(p::Person)
    println("Hi, my name is $(p.name) and I am a $(p.age)-year-old $(p.occupation).")
end

p1 = Person("Alice", 25, "Software Engineer")
introduce(p1)

As far as I understood, after correcting the code, the introduce function is just a normal function and not a custom method of struct Person.
