Problems with the text un AE

Good afternoon;
I can’t find a way to create an animation with text, in this case a timer. If it was a word, it can be done by converting the text layer into a shape layer. In a two-minute timer it is impossible, it would be 120 layers and animate them one by one. Any solution?.
Strange that something so easy to do in After Effects turns out to be a complicated tab to convert.
Thanks!!!
