how to detect slow coroutine

[vipcxj]

Is there a way to detect a particularly slow coroutine. It is always known that a coroutine should not block. However, once a project is complex enough, the chances of erroneous blocking of a coroutine are inevitable. I need a way to detect where asynchronous code is incorrectly introducing blocking. The detection criterion is that the execution time exceeds a certain value.
I hope this approach provides two pieces of information

1. Duration of the slow coroutine
2. Source code location of the slow coroutine

After some research, I found out that customizing an executor should enable the task of finding the slow coroutine to some extent. However, this approach makes it difficult to get information about the source location of the coroutine. Is there a better, less intrusive method?
