How to use better-exceptions in pytest?

Pytest is the most popular testing framework in Python. I want to enhance its error logging, just like #76.
Here's my code:
import better_exceptions
from pytest import ExceptionInfo
def patch(exc_info, exprinfo):
tb = exc_info[2]
# max_traceback_limit(tb)
# traceback is staring from the root cause. deal it in the end.
# rich.print(tb)
# breakpoint()
cls = ExceptionInfo
textlist = better_exceptions.format_exception(
exc=exc_info[0], value=exc_info[1], tb=tb)
# textlist = better_exceptions.format_exception(*exc_info)
text = "".join(textlist)
keyword = "in pytest_pyfunc_call"
text = text.split("\n")
last_index = -20
for i, t in enumerate(text):
if keyword in t:
last_index = i
break
text = text[last_index:]
text = "\n".join(text)
print()
print(text) # great. this could be the hook.
return cls(exc_info, text, _ispytest=True)
ExceptionInfo.from_exc_info = patch
This code will not replace the original formatting of exceptions in Pytest, just print its own error info side by side. I want to know if there are better ways to do so, also builtin hook supports?
