Add Basic Features to app created in Unity 3D

Hello, I have a template made with unity, is good and basic but it lacks some details that I want to add as they are: Rate App/ Valorar App Privacy Policy (opens a link in the browser to a url, usually [login to view URL]) Recommended Apps (Opens my developer store with all my apps) Share app (which opens the sharing option on your device and sends a default text and link to the application on Google play) Right now the only settings you have are these: [login to view URL] and I'd like to add what I've told you there by adding more settings, or you could also create a kind of menu at the top where the exit button is: [login to view URL] Instead of the button Exit then a kind of menu with all these options and add there the option Exit not to remove it. The idea I like the most is to add it in the settings they already have, besides moving the exit button to those settings, because when they want to modify the volume or want to exit they always see it.
