Adjusting starting position for running announcement bar

I’m using Essential Announcer App for these two lines/announcement bars and I have it set to a running announcement, but the thing is I don’t want it to continuously be running in. What I noticed in the code was that it was designed in a way where it just has multiple copies of the same text and then just feeds them down the line.

What I want is for it first to start blank and then the first wave comes in from the right slowly and then fills the bar, the way it is right now is that the first line starts all the way on the left and the bar already looks full, how can I change it so that it starts on the right side instead?

If this app is free and does not effect site performance than it’s ok otherwise you did not have to use an app for this, this can be achieved with a bit of coding and also giving you the ability to choose sides.
