What do you add to the daily prayers on the 10 days of repentance? (SEE TEXT BELOW)

I’m pretty new to practicing Judaism (wasn’t religious before and got into the religion more now), and now that Rosh Hashana has finished, what do I add on the 10 days of repentance to the daily prayers? I know you add Hallel in morning and you add lines on kaddish and the Amidah, but is there anything I’m missing? Any help is good help thanks!
