When you text someone for the first time ever and then you e been texting for days. How do you get back to the very first text you sent them or they sent you ?

When you text someone for the first time ever. How do you get back to the very beginning of the conversation without having to scroll backwards all the way to the beginning which can take forever to do. Was wondering if there was an easier way to get back to the first texts sent when a person first ever started texting someone. Thank you ! ☺️
