Phone browsers cannot talk to wallet apps directly. When no wallet is found, the connect window shows Open this page in your wallet app. Tap your wallet and the page opens inside it, ready to connect.
Phantom and Solflare (Solana) and MetaMask, Trust Wallet and OKX Wallet (EVM) have these links. If the app is not installed, the link sends you to its download page. For Binance Wallet, open memewar.zone from the Discover tab of the app.
