How to stop merge of branches which is in progress already?

How to stop merge of branches which is in progress already?

I am in such situation:

There is last conflict to be resolved before the merge would be done, but I need this merge not to happen at all.

This unfinished merge is blocking the branch which is used also by other developers (the branch continues development) for me now, so I need to stop it urgently.

How?

Hi @lukas.danek

‘Discard draft’ should do the trick
