Agentic Chat is not available in Gitlab's web IDE, though standard Duo Chat is available. The Web IDE is based on VS Code and is released by the GitLab team, so it should be able to support all of our features, including one that has recently been made generally available and have been pushing as our newest premiere offering. <!-- Label reminders Use the following resources to find the appropriate labels: - Use only one tier label choosing the lowest tier this is intended for - https://gitlab.com/gitlab-org/gitlab/-/labels - https://about.gitlab.com/handbook/product/categories/features/ -->
