Thank you for your question!
Based on the documentation, deleting nodes is usually done by selecting the node and pressing Backspace, but there is no specific mention of End Call (Hangup) nodes.
Could you let me know if pressing Backspace after selecting the End Call node has any effect, or if you see any error or UI feedback when you try this? This will help determine if it's a UI limitation or a possible bug.
