How can I parse a cookie with a dynamic name?

[PepeHands]

Hello, I've got a cookie that I need to parse which has a dynamic name. I know that I need to parse this cookie since it's the 4th cookie that I receive when I make this request. How can I do this in Openbullet?
I've got 2 examples here below to show you guys what I mean. I need to capture the 4th cookie here.

Parse both key and value

[Ruri]

If the value is fixed, you can parse by value <COOKIES{value}>

[Ruri]

Otherwise just use <COOKIES> which will return a stringified version of the cookie dictionary and then make a regex that will parse the cookie you need from that string.

@Ruri Do you know how I can make the regex? I've never used regex parsing before

[Ruri]

You should show me an example of your <COOKIES> variable and what exactly you want to parse (and exactly what is randomized each time)

Examples are above. You can see that the variable names are randomised and I need to capture the respective JWTs. I don't want to paste all the cookies since that would probably clutter everything up. You can see two examples of <COOKIES> in the imgur link here. https://imgur.com/a/yBbjHGA

whats difference between () and {} in <COOKIES()>

You could do something like parse ey[0-9A-Za-z]+ to parse the jwt (output would be [0])
