Hyperlink to a hidden sheet in a same workbook

I attached a sample of my excel file.I need to hide the tabs Part1 to Part5 and link them to the Main Tab that I called "Menu". u can access all the hidden tabs from the menu tab through hyperlinks that i created and then u have the button back on each tab (part1 to part5 ) to bring u back to the Menu Tab. the issue is that the hyperlink is not working when u hide the tabs (part1 to Part5). I tried different things on VBA. plz any help will be appreciated.
