Convert string to date (edge case) in Bigquery

Question

I have a column with a list of strings in a column that represent date and time, but the time is attached to the date with no space. I'm having trouble identifying the correct query to convert to datetime.

The original strings look like this:

April 22, 20229:00am 
 October 19, 202012:00pm 
 April 12, 20225:00pm 

I would like them to be in the date/time format:

April 22, 2022 9:00am 
 October 19, 2020 12:00pm 
 April 12, 2022 5:00pm
