Pretty sure you can’t, sorry mate
Go to ur homepage and scroll down to where ur comments are. Click on ur comment, then you'll see ur comment and options like "edit" and "delete" will be there
Press that three lines thing beside the notification bell on the main screen, go to timeline, it shows all your activities (comments and etc), click on the comment you want to delete. There should be both edit and delete option under the comment/topic on the manga/manhwa.
Not sure if this is what you asked for but yeah-
