It's not about delaying the data,  it's about delaying the display

For example, if the data transmitted is 2, I want it to be updated to 2 after 5 seconds.

Trigger a scene-director that has a 5 second pause in it before it displays the data

Yes.  What was said above. - You go into the text object that is going to update, or just a dummy one.  Then there, there is a script item for "OnSetText".  And so when the text changes it will do whatever you put into the script. In this case, you can want the text to change.  So I would have the text, then I would have a dummy text.  When the text changes, a scene director runs to update the text, but 5 seconds later, on the dummy text.  That way the source data is never actually the text that is online.
