importing package from git link

I'm trying to import a package from a git link

(https://bitbucket.org/UnityUIExtensions/unity-ui-extensions/src/release/) (https://bitbucket.org/UnityUIExtensions/unity-ui-extensions.git)

But whenever I try this, Unity gives 2 errors stating:

Cannot perform upm operation: Unable to add package [https://bitbucket.org/UnityUIExtensions/unity-ui-extensions.git]: No 'git' executable was found. Please install Git on your system then restart Unity and Unity Hub [NotFound] UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

and

Error adding package: . UnityEditor.EditorApplication:Internal_CallUpdateFunctions()

I installed Git, and added two PATHs:

one to an .exe: C:\Program Files\Git\bin\git.exe and one to a folder: C:\Program Files\Git\cmd

Which is where my Git is installed. Does anyone have an idea what I'm doing wrong?
