Welcome, confused_g.
It sounds as though you have a bulbous type of iris. They do go dormant and they can come back. But probably not until next winter. You may see new green growth and then early
spring new blooms. Meanwhile don't water that pot too much or the bulbs will rot. Barely damp at all is best. Store it in a cool dark place, basement or closet. Next winter, around January, bring it out and put it in your sunniest window, and water lightly. See what happens.
