Regexextract not working with non-capturing groups or with lookahead/lookbehind

Hi here,

I have strings with variable length and I need to extract a certain pattern into a custom column.

Sample string (I need the digits after the last underscore):
AV11_V242_240214_173019_105335
Output would be: 105335

A regex that works at regex101.com:
(?:([a-zA-Z0-9]{4}))(?:([a-zA-Z0-9]{3,4}))(?:([0-9]{6}))(?:([0-9]{6}))(.*)

But this does not work at Metabase on a custom field.
I've also tried regex lookahead and lookbehind but those dont work either.

Any ideas?

Thanks
