Custom traceback is being overridden when importing exceptiongroup

I took as a reference the source code of exceptiongroup in order to make a custom exception of my own with a custom traceback .

It worked as expected, the thing is, when I import exceptiongroup, it overrides the traceback exception from the exceptiongroup.

Is there a way to isolate my implementation?

I assume it relates to this code:

https://github.com/agronholm/exceptiongroup/blob/4e2df2190d3c61a2e7940d6908b32658dfadab3f/src/exceptiongroup/_formatting.py#L343-L360

What can I do about it?
