smetana is not recognized as int or ext command, program or batch file in anaconda prompt in windows 11

I created an environment with python 3.6, installed python-libsbml seperately (as it was not being installed while running 'pip install smetana'). Then I installed smetana using 'pip install smetana'. I added the /anaconda3/envs/<env_name>/lib/site_packages/smetana/ in system path variable. Still I am getting this error msg: "smetana is not recognized as an internal or external command, operable program or batch file" whenever I run 'smetana *.xml' in the newly created environment in anaconda prompt in windows 11.
