Answer:
The process is called installing third-party applications.
Step-by-step explanation:
Giving any permissions to a third-party app means that from now on the app can get information from your OS and take it to the cloud without explicitly consenting to what it intends to do with your data.
Therefore, we recommend that you stop and think before granting app permissions, especially if they are not required for the app to function. For example, most games don't have to access your contacts or camera, messaging apps don't really need to know your location, and some modern camera filters can probably survive without your browsing history.
