golarion – What is required, system-wise, for a character to be a member of the Pathfinder Society?

The Pathfinder Society organization is introduced in the Character Guide handbook, and it says the following on page 108:

Membership Requirements present oneself at the Grand Lodge in Absalom, prove one’s aptitude in physical and mental challenges, undergo arduous training under the Masters, and pass the test of Confirmation; alternatively, earn a field commission through outstanding efforts

If you’re creating a new character, do you just have to say “I did that” to gain access to game elements that require you to be a member of the Pathfinder Society? For example a Pathfinder’s Pouch.

According to the same handbook, on page 106:

Once approved, a Pathfinder initiate undergoes an individually tailored test called the Confirmation. In many ways, this test acts as the initiate’s first mission as a Pathfinder, and afterward the initiate becomes a field agent—a true Pathfinder, with equal status to all other agents.

So, in order to become a member you must pass the Confirmation. And after passing the Confirmation you become an agent. Ergo, every member of the Pathfinder Society is a Pathfinder Agent then?

Then why does the Pathfinder Agent dedication feat require you to be a member of the Pathfinder Society?

Do you need the Pathfinder Agent archetype in order to access things that require you to be a member of the Pathfinder Society?
