Is there any way to add a custom icon

I am using vue-feather-icon and there are countable icons on it just apx 285. I want to add my custom icons on it related to accounting. like Chart of Accounts icon, Cheques icon, Accounts Management icons etc.
Please help me regarding this

The issue names vue-feather-icon and accounting icons but no repository file, test, or entry point. First inspect the project’s icon contribution or extension guidance; the definition of done requires clarifying the supported approach and the required accounting icon set.
