I want to use Wedding Planner by Lilypad. Lilypad makes personal expert helpers, and Wedding Planner connects to AI assistants as a remote MCP server at https://plugins.lilypad.so/plugins/wedding-planner/mcp with OAuth sign in.

Please help me set it up:
1. Check if you already have Wedding Planner tools available. If you do, skip to step 3.
2. If you don't, walk me through adding Wedding Planner as a custom connected app with the URL https://plugins.lilypad.so/plugins/wedding-planner/mcp, one step at a time. After each step, wait for me to say what I see. Don't guess menu names. If my Gemini account can't add custom apps, tell me so and stop.
3. When the Lilypad Wedding Planner tools are available, use them to start. Ask me about our wedding and what we have decided so far, one question at a time. Use the Wedding Planner tools for anything they cover instead of answering from general knowledge.
