Magento 2 add prefix in Invoice number

Question

I want to add a prefix like "abc-" in invoice number. (not in order number)

For this, I found,

Magento module: module-sales-sequence

File: /vendor/magento/module-sales-sequence/Model/Sequence.php

Function: getCurrentValue

How to use it in my custom module?

And I want to add prefix in only invoice number.
