Create unique reference ID

[MoEdu]

I have a column name ReferenceID on a SP list, what I would like to do is each time an item is created in list A for the referenceID to be auto generated as ABC1 ABC2 ABC2 and so forth

This is part of a bigger flow which I am building which is as follows:

1. when an item is created in list A create in list B

2. when an item is modified in list B update list A

Could anyone kindly explain how I can achieve this in flow?
