Hi there, k-ousman.
I can see how helpful it would be to add apps in your QuickBooks account. QuickBooks added the Apps menu on the left navigation bar. However, this feature is not yet working in the international version of QBO. That's the reason you're unable to add apps. It only works in the United States, United Kingdom, Canada, India, Australia, and France QuickBooks Online version.
I suggest visiting our QuickBooks Blog to know about the latest news and updates from QuickBooks Online. Aside from that, we have Help articles that provide step-by-step details on which section of QuickBooks you need help with.
Always know that the Community is always ready to assist you if you have other questions related to QuickBooks. You stay safe and you take care. Have a great one!
