Get the remaining time duration

so I've created a google sheet wherein on Column A I have a date and a time (01/05/2023 14:46:89 | Yesterday's date and time) Something like this and on Column B, I have (01/06/2023 16:46:00 | Today's date and time)

What I want is to display the remaining time on Column C from column B time how many minutes before reaching the time in column A.

Lastly is, for example, I only have like 5 minutes left before reaching the same time on column A, I want to display a text on column D something like "almost there".

Is this even possible? Thank you.

I want to do it using an "ArrayFormula".
