Good morning, I am following the development tutorial in chapter 3: 'A new application', I create the estate directory with the __init__.py and __manifest__.py files. This is the manifest code: { 'name': 'Real Estate', 'depends':['base'], 'application': True}. The module appears to me with all the other modules, but when activated it should appear in the square button at the top left. Someone help me, because I can't access the module and continue with the tutorial. Thank you
