Dialogue menus are turned on a different way to regular Menus - you instead set the "Appear type" to "During Conversation", and it'll then appear automatically whenever you initiate a Conversation using "Dialogue: Start conversation".
You can modify / copy from the default Menu Manager's Conversation Menu - it's easier than starting from scratch.
For that i used appear type "When Speech Plays". I want to add next button (in this menu) to switch to the next speech and dont wait, but game is freezing during this speech.
I turn on "Play in background" and return to problem: all hotspots in a background is active.
Currently, Menus don't respond to clicks while you're in a cutscene. If you want to disable Hotspots during gameplay, then you can use the Engine: Manage systems Action to disable the "Interactions" system.

If you're using scrolling text, and want to pause mid-speech, you can insert e.g. [wait:2] to wait for 2 seconds into the speech text box directly.
