After acquiring the app via Salesforce AppExchange, the Org gets several app licenses. These licenses need to be assigned to respective users so they can work with the app. There are a few steps to take here:
Go to Setup.
Search for Installed Packages and open the equally named setting.

Find the Maven Documents entry in the Installed Packages list, and click on Manage Licenses.
Click the Add Users button and select users by marking checkboxes next to their names.

If the user has no license assigned, they can't generate documents.
There is also fair usage in place for every user.
The next thing to do is to give certain rights to individual users. The following types of permission sets come with the package:
Once the Maven Documents Extended permission set is created, the administrator needs to assign it to the users who will work with Maven Documents.
Assigning permission sets to users can be done in a few simple steps.
Click on the Manage Assignments button.

Click the Add Assignment button which leads you to the process of selecting the corresponding user.

Mark the checkbox on the left of the User's name to choose which users to apply the permission set for and click Next.

On the next screen, you will be able to set the expiration date for the permission set or leave the default setting with no time limit.
Once you have selected all the Users for the permission set and the time frame for those settings, click Assign. That's it, the permission sets are assigned to the appropriate Users.

There’s an option to automate the permissions management process. User Access Policies is the native Salesforce feature that simplifies the work with permissions and makes it more secure and less error-prone.
Here’s a quick manual on implementing this feature in your work process.
On the Setup page, under User Management Settings, enable User Access Policies.

After User Access Policies appear in the list of settings, select it and click New User Access Policy.

Give the new User Access Policy a name and then click Save.
In the created policy, click Edit Criteria.

Set the needed filters in the respective fields and save the Policy.
