Last Entry of Dialogue displayed in separate Text (Scriptable objects)

Hello Everyone,

I'm a new programmer and i was hoping that you will help. (also my English isn't very Good :D)

I have a dialogue made of Scriptable Objects. each scriptable object is like a group with texts and responses (which are options). when the player chooses an option, it takes them to another group of texts. it looks like a mobile app.

It works great. However, i want to make a separate text that shows the last entry (also like a mobile app) but i can't figure out how to take a text from scriptable object and show it in another text when it's displayed!

I tried to put the same code of the dialogue and delete the instantiated parts. it displayed the texts of the first group (and not the responses) then it stopped.

I want the text stays at the last message displayed. then when the player choose an option, it displays the response text and go to the other group of texts that are connected to this response and so on...

Can anyone help me with this? Thanks in advance :)
