- 目标用户
- bellFace video conferencing users / ベスト会議pro (Best Meeting pro) video conferencing users / Japanese business users of web-based video meeting services
- No Chrome Web Store detail available (fetch error), so product description/reviews could not confirm functionality
- manifest_bestMtg.json is a secondary manifest not used by the installed extension (main manifest.json is for bellFace); it may be a variant build for a sibling product
- Cannot verify from extension code alone whether the destination services require login or have paid tiers
付费分析未识别到付费功能
The extension contains no payment, billing, subscription, or premium-gating code. No Stripe, no license checks, no upgrade prompts. The keyword 'pro' hit in manifest_bestMtg.json (line 32) refers to the destination service name 'ベスト会議pro' (Best Meeting pro), not a paid feature within the extension. The extension is a free helper that adds screen sharing via chrome.desktopCapture API regardless of the user's service plan.

- The extension itself has no login UI or auth code. However, it is a helper extension for bellFace (bell-face.com) and ベスト会議pro (best-mtg.com), which are web-based video conferencing services accessible at user.bell-face.com/* and user.best-mtg.com/*. To use the screen sharing feature, the user must be logged into one of these destination services, as the extension only activates when it receives external messages from those web apps (bg.js line 4: chrome.runtime.onMessageExternal). The extension cannot function independently of the destination service.
