3 day potty training method

If youve done this can you give me some tips and advice please. How did it go for you? What should i expect? Dos and donts. Is it realistic to actually teach them in 3 days? Or would it be better to do it in a longer stretch of time? I really want to potty train my son (my first child). I have no idea what to do and since he is in Easter break i thought it would be a good time to do it. He is 4 years old and in a special ed school where they teach them how to pull their pull ups down, not be scared of toilets, wash their hands, etc but not actually potty train. Hes not very vocal and only talks in short sentences (E.X gibberish, gibberish, gibberish, peanut butter jelly sandwich, gibberish, gibberish) but he is very smart, loves to learn, and understands me when i ask him to do something or when i ask him a question. He is no longer scared of the toilet and SOMETIMES tries to change himself but he still has no interest in the toilet. Would it be better to do it during summer break with more time or could this be done during spring break?? We got him paw patrol undies and a paw patrol toilet topper thing to sit on. Im not sure what its called 😂. Anyways, thanks ladies for any advice and tips.
