How do I install pipx on windows?

I'm currently trying to follow the guides from CumulusCi and I'm having some trouble installing pipx inside my computer.

I already have installed Python 3 and I'm currently running the following command:

pip install --user pipx

'''

The result is the following:

Requirement already satisfied:

pipx in c:\users\aharo\appdata\roaming\python\python39\site-packages (0.16.1.0)

I set up the path environmental variables, and when I'm running pipx list is telling me the following:

pipx : The term 'pipx' is not recognized as the name of a cmdlet, function, script file, or operable program. Check
the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:1
+ pipx list
+ ~~~~
    + CategoryInfo          : ObjectNotFound: (pipx:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

Does anyone know how to solve this issue?
