I have use
regex_extract(string, '(([a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12})|([a-fA-F0-9]{8}[a-fA-F0-9]{4}[a-fA-F0-9]{4}[a-fA-F0-9]{4}[a-fA-F0-9]{12})), 1)
and also string split separated by (,) to capture second among following UUIDs which are together but I don't know what am missing. Actually I need to capture both!!
