on any place, you can use clash (or mihomo) for proxy routing

here I give you a configure of it

```

port: 7890

mode: rule

external-controller: 127.0.0.1:9090

proxies:

- name: i2p

type: http

server: 127.0.0.1

port: 4444

rules:

- DOMAIN-SUFFIX,i2p,i2p

```

or just use a web client with browser proxy plugin
