changing order of elements in a filename

Hi, I have this pattern: date_username_code_sequence and want the username to come first.

Examples:
2023-04-21_User01_1226392686502063109_0.jpg would be User01_2023-04-21_1226392686502063109_0.jpg
2021-10-11_Username_here_1226392686502026109_0.jpg would be Username_here_2021-10-11_1226392686502026109_0.jpg

where _ is used as separator, date, code and sequence always have the same length, but the username can change length and even include a _ on it.

Can someone help me? Thanks.

Replace: ^([^_]*_)(.*_)(\d*_\d*)
with: \2\1\3
Use regular expressions
