Golang positive lookahead alternative

I need to add a password check pattern to the json schema that Golang handles.

• At least one digit At least one lowercase character
• At least one uppercase character
• At least one special character
• At least 8 characters in length, but no more than 32.

The pattern doesn't work because Golang doesn't support positive lookahead

^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[#%$!*+=_@-])[A-Za-z0-9#%$!*+=_-]{8,32}$

How to change the pattern to keep the password verification conditions and not use positive lookahead.
