I have python installed through windows store and I can install programs using pip, but when I try to run said programs, they fail to execute in powershell.
How can I make sure that the necessary "scripts" folder is in my path? I never faced these problems when installing from executable.
For example, "pip install ntfy" runs successfully in Powershell.
The command "ntfy send test" fails telling me the term is not part of a cmdlet, function, etc. etc.
The 'ntfy' program is  located here /mnt/c/Users/vlouvet/AppData/Local/Packages/PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0/LocalCache/local-packages/Python37/Scripts/ntfy.exe
What is the recommended way of editing my path so that programs installed via pip are available across windows store updates of the Python language?
The above answer is good but I managed to get it to work by doing the following.

Find your installation under C:\Users\"your user"\AppData\Local\Packages it will be named something like PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0
Open your windows settings in the start menu
In search type Environment variables. Edit environment variables for your account should pop up. Click it
In the top box find Path, click it
On the right Click new and enter C:\Users\"your user"\AppData\Local\Packages\"python install directory name from 1. here"\LocalCache\local-packages\Python37\Scripts inside the little box under the last item in the list
open a new cmd prompt and type the script you wanted it should work.
