Creates and initializes a browser session in Amazon Bedrock AgentCore. The session enables agents to navigate and interact with web content, extract information from websites, and perform web-based tasks as part of their response generation.

To create a session, you must specify a browser identifier and a name. You can also configure the viewport dimensions to control the visible area of web content. The session remains active until it times out or you explicitly stop it using the StopBrowserSession operation.

The following operations are related to StartBrowserSession:

put/browsers/{browserIdentifier}/sessions/start

The name of the browser session. This name helps you identify and manage the session. The name does not need to be unique.
