how to click connect line

There is an option to allow you to click on the connection line between the two items in the diagram.

But the line is too thin to click, is it possible to improve the function on this part?? Or are there any scheduled feature improvements related to this??

Currently we’re not planning to change the current behavior but I’ve sent your request to the dev team and it will be observed, so the probable solution may appear in the future updates.
I’ll inform you about any possible progress on this feature.
