I found the step by step description here, seemed a bit cumbersome, so I automated it, at least for a Windows environment. Comments welcome:

dirName = f'python-{platform.python_version()}-embed-amd64'
localappdatapath = os.getenv(r'LOCALAPPDATA')
dirPath = os.path.join(localappdatapath, dirName)
assert os.path.isdir(dirPath)
bootstrapPipFilePath = os.path.join(dirPath, 'get-pip.py')
if not os.path.isfile(bootstrapPipFilePath):
    WebClient().DownloadFile('https://bootstrap.pypa.io/get-pip.py', bootstrapPipFilePath)
pthFilePath = os.path.join(dirPath, 'python38._pth')
assert os.path.isfile(pthFilePath)
replace = False
with open(pthFilePath, 'r') as f:
    lines = f.readlines()
    if '#' in lines[-1]: 
        lines[-1] = lines[-1].replace('#','')
        replace = True
if replace:
    with open(pthFilePath, 'w') as f:
        f.writelines(lines)
pipDirPath = os.path.join(dirPath, 'Scripts')
if not os.path.isdir(pipDirPath):
    OUT = f'installing pip in local Python environment: {dirPath}'
    batPath = os.path.join(localappdatapath,'Temp', 'pipInstall.bat')
    with open(batPath, 'w') as f:
        f.write(f'cd {dirPath}\n')
        f.write('python get-pip.py')
    try: subprocess.run(batPath, check = True) #check argument raises exception when an error occurs
    except Exception as ex:
        OUT += '\n error while installing pip:'
        OUT += '\n' + str(ex)
    else: 
        os.remove(batPath)
        OUT += '\n pip succesfully installed'
else: OUT = 'pip was already installed for this local Python environment'

installPackages = IN[0]
if installPackages:
    sys.path.append(os.path.join(localappdatapath, r'python-3.8.3-embed-amd64\Lib\site-packages'))
    for packageName in installPackages:
        spec = importlib.util.find_spec( packageName )
        if spec is None: 
            OUT += f'\n installing {packageName} in local Python environment: {dirPath}'
            batPath = os.path.join(localappdatapath,'Temp', packageName+'Install.bat')
            with open(batPath, 'w') as f:
                f.write(f'cd {dirPath}\n')
                f.write('.\Scripts\pip install '+packageName)
            try: subprocess.run(batPath, check = True) #check argument raises exception when an error occurs
            except Exception as ex:
