The Flex Plugins CLI can be upgraded using the Twilio CLI. Your first step is keeping the Twilio CLI up-to-date. Details are available in the CLI Quickstart Guide. The Twilio CLI will always report if a new version is available when you are executing twilio commands.
The Flex Plugin CLI can be updated using the original install command used when setting up your development environment.
1$ npm show @twilio-labs/plugin-flex24.8.0
1$ twilio plugins2@twilio-labs/plugin-flex 1.0.0
twilio plugins:install @twilio-labs/plugin-flex
