Add the following classes to the Advanced CSS Classes field:

```auto
[&_blockquote]:border-l-4 
[&_blockquote]:border-surface-600 
[&_blockquote]:pl-4

```

You can customise the border with any Tailwind colour, the example above is using surface-600, you could switch it to the brand colour and change the shade using the number on the end:

```auto
[&_blockquote]:border-brand-500 

```
