Check out typewriter plugin. It is for sure the easiest way.
If you have special requirements regarding animation of the text, do the following:
Create a text element.
Add a state “xyz” to the text element of type number
Add conditions to the text element that change the text depending on the xyz number
if text.xyz = 1 then text = “Text 1”; if text.xyz = 2 then text = “Text 2”; …
Under workflows, add an event “Do every X seconds”. Under this event increase the number of xyz (Set state of text.xyz = text.xyz + 1)
