How do I create an Access Token for myself as an Administrator?

Historically we leveraged an employee with the Administrator role to manage our integrations.

This employee is leaving so we are setting up a generic user with integration related roles, including Administrator. This "Integration User" has additional roles assigned to it.

I am logged in as that generic person "Integration User", Administrator.

I know that the Administrator cannot create access tokens for another Administrator but I am trying to create an access token for myself logged in as the "Integration User."

When I attempt to create an Access Token, the Administrator role is not available.

A couple questions:

Is there a better recommended procedure to integrate applications than using an Employee with Administrator role? If there is a better recommendation, would you provide me the steps or related SuiteAnswer?
