Help to setup Chrome flags if needed

This page demonstrates the core features of the Gemini Nano Prompt API (`LanguageModel` API) available in Chrome 138+. Ensure you have enabled the necessary flags. Copy the link below and paste it into your Chrome address bar: Copy - tab
Then set #optimization-guide-on-device-model (to Enabled BypassPrefRequirement)
Then search for and set all of them to enabled:

1. #prompt-api-for-gemini-nano (set to Enabled)
2. #prompt-api-for-gemini-nano-multimodal-input(set to Enabled)
3. #summarization-api-for-gemini-nano(set to Enabled)
4. #writer-api-for-gemini-nano(set to Enabled)
5. #rewriter-api-for-gemini-nano(set to Enabled)
6. #proofreader-api-for-gemini-nano(set to Enabled)

The Gemini Nano model will download the first time you use it. That will be about 4.0 GB of download and will need about 20 GB saving space for the final folders.
