I am adding profiler on my custom method on Odoo v15.0

I have referred below doc for code profiling

https://www.odoo.com/documentation/15.0/developer/howtos/profilecode.html

Below is the syntax i am using 

from odoo.tools.profiler import profile
[...]
@profile
@api.model
def mymethod(...):

But on execution of code i am getting below error on terminal

ImportError: cannot import name 'profile' from 'odoo.tools.profiler'

To debug the issue i have deep dived in base code of /odoo/tool/profiler.py  But unable to locate any wrapper or function called profiler.

What is correct way to use profiling using "Log a method" strategy on  odoo v15.0?
