Hi @varuna82lk! 

I’ll do my best to help you with your question! 

Do I understand correctly that you wish to add a link like on this screenshot? Have you tried Insert link feature from the context menu?

You can also link nodes on your Mind map using the Link to option from the context menu. Here's how you can do this:

1. Click the node you'd like to link to another one > choose Copy link from the context menu;
2. Click the other node on the mind map > open the context menu and choose Link to > enter the link to the first node.

Please let me know if I miss anything!
