 It returns a tuple containing text without any entities, and the entities
 themselves (if applicable). If `text` was not provided, empty string

+## Fully custom requests
+
+mtcute also allows you to send fully custom requests to the server.
+This is useful if you want to use some undocumented or yet-unreleased APIs
+and don't want to patch the library or use the TL schema override mechanism.
+
+You can use the `mtcute.customRequest` pseudo-method for that:
+
+```ts
+const res = await tg.call({
+    _: 'mtcute.customRequest',
+    bytes: Buffer.from('11223344', 'hex'),
+})
+```
+
+`bytes` will be send as-is to the server, and the response will be returned as a `Uint8Array`
+for you to handle on your own (it might be useful to look into [`@mtcute/tl-runtime` package](https://ref.mtcute.dev/modules/_mtcute_tl_runtime.html))
