⚡ Recommended focus areas for review Restrictive Configuration Pattern 🟠 [major] The new pattern for snyk.advanced.customEndpoint is overly restrictive. It requires the URL to start with api and end with snyk.io or snykgov.io. This will break configurations for users with private instances (Single Tenant) or internal development environments that use different domain structures, contradicting the markdownDescription which states the setting is for private instances. "pattern": "^(|(https?://)api.*.(snyk|snykgov).io)$", Unsafe Optional Chaining 🟡 [minor] In the SNYK_SETTINGS_COMMAND registration, the code now calls this.workspaceConfigurationProvider?.showPanel(). If workspaceConfigurationProvider fails to initialize (e.g., due to a failure in initializeExtension), clicking the settings icon will do nothing silently, and the previous fallback to commandController.openSettings() has been removed. await this.workspaceConfigurationProvider?.showPanel();
