Please explain the entire process. I would like to understand it clearly so that someone can effectively support you.

I want create multi sale_order_line of the similar products.
Step to reproduce:
- Create an event with a paid ticket
- Go to the website and register 2 similar tickets for 2 people
- Go to the cart.
=> Expected: 2 line for 2 ticket

Example: In my event, I have 2 type of ticket: STANDARD and VIP.
I bought 2 tickets VIP and I want when I redirect to /shop/cart: its show 2 line (instead of 1 line)
