You can create an unlicensed application user in your environment. This application user will be given access to your environment’s data on behalf of the user who’s using your application.
Note: In an environment, you can only have one application user for each Azure AD–registered application.
Follow the below steps to create an Application User in Dynamics 365 CE online environment.
Pre-requisite: Follow the below article and Register an App in Azure AD.
If you have already registered an App in Azure Active Directory, then go to Step 1.
Step 1: Login to Power Platform Admin Center (PPAC) with your credentials.
If you are using US Government (GCC, GCC High and DOD) Cloud, click on the article link and find your related URL and login to PPAC.
Step 2: Click on Environments.
Step 3: Click on required Environment, where you would like to create an Application User.
Step 4: Click on Settings.

In this example, I am selecting System Administrator.
Note: In general scenarios, do not provide System Administrator access to the Application user, instead create a customized security role(s) that restricts access to the limited data of your application.
Step 13: Click on Create.
Application user has been created successfully.
