Need help making a dialogue window keybinding addon

[Photron101]

Im learning how to make addons for wow for myself at the moment. i made two addons that have a window popup like the hello world message function essentially. which is the first
and second one uses the events in game functions and makes a pop up window each time a character is leveled up.

Im trying to make an addon similar to DialogKey. I have DialogKey DF which is the most up to date version, however it will not let me add to the Dialog if this appears let these functions run.

Im just needing help making a simple version. If a dialogue window pops up with one button or multiple- i can either tap space bar or one of the numbers on keyboard to put it as simply as can.
