Help with rex- How do separate this event that came at the same time but different values?

[Italy1358]

I have an event that came in the same time but have different data values that I need to separate. 

Example

_time	example A
2022-09-02	dgde746gdhu4 duyheuye4d0

I need this:

_time	example A
2022-09-02	dgde746gdhu4
2022-09-02	duyheuye4d0

Use the mvexpand command to separate the values of the example A field into separate events.

| mvexpand 'example A'
