Using FME 2021, I am trying ton import ArcGIS Python API package into FME to be able to use  from arcgis.gis import GIS

I used CMD and ran the following command

C:\Users\User\Documents\FME\Plugins\Python>fme.exe python -m pip install arcgis

but I am getting this error

    ERROR: Command errored out with exit status 1:
