show how to react to a comment / edit, suppress a comment on mobile app

Hello, on the mobile app when you want to reply to someone's comment, it takes a lot of imagination to understand how… they have to figure out that they are supposed to press 3 secondes (that's long) on the comment to have a window open that proposes to reply. My community is made of 60% of people over 60. They just dont get it and i have to answer them 20 times per week on that matter. If they want to edit or suppress their own comment, again, it' s not intuitive at all… Please can you add 3 dots… ?
