gganimate + event study graph gif

I have the following data and code. My ultimate purpose is to recreate the gif I am attaching. I want to animate the ggplot graph that I created and then, save a gif. I want the transition to be smooth on t_es (the line appearing as it advances) and then, stop for a really short time when t_es = 0, and then keep going smooth. While I do animate the plot, I am not achieving it to stop a tiny bit when t_es = 0.
