A more thorough explanation:

A public session is a meeting or gathering that is open to the general public. It is the opposite of a private session, which is closed to the public. During a public session, anyone can attend and observe what is happening.

For example, a city council meeting may be a public session where citizens can attend and voice their opinions on issues affecting the community. Another example is a public hearing held by a government agency to gather feedback on a proposed policy or regulation.

Public sessions are important for promoting transparency and accountability in government and other organizations. They allow the public to stay informed and participate in the decision-making process.
