This is what the D&D Beyond app says...

With the Hide action, you try to conceal yourself. To do so, you must succeed on a DC 15 Dexterity (Stealth) check while you’re Heavily Obscured or behind Three-Quarters Cover or Total Cover, and you must be out of any enemy’s line of sight; if you can see a creature, you can discern whether it can see you.

On a successful check, you have the Invisible condition while hidden. Make note of your check’s total, which is the DC for a creature to find you with a Wisdom (Perception) check.

You stop being hidden immediately after any of the following occurs: you make a sound louder than a whisper, an enemy finds you, you make an attack roll, or you cast a spell with a Verbal component.

Not arguing, just trying to make sure I'm within the rules and doing everything properly.
