Show Notification according to selected line in listview

Dear friends of the forum, I have not found similar examples, what I want is that when selecting a line with double click the userform is shown with the textbox with the corresponding notification in column K
and that to update the data, do it in the same cell that corresponds
I have noticed that here they have experience in the listview control and I am sure I have some help collaboration
Thanks in advance
I upload a file to be seen

Maybe it will be that this topic has no solution?
Can someone explain me why not?
