Found black zip pouch with orange zipper

I found this morning around 9:15am along the Riverwalk near the Friendship Fountain in downtown Jacksonville. It's a small black zippered pouch about 6x4 inches, made of nylon, with an eye-catching orange zipper pull and a tiny enamel dolphin pin on the outside. Inside there's a black USB-C cable, a compact white power bank, and a crumpled coffee-shop receipt. The pouch looks gently used but intact, and the river breeze carried a faint citrus scent. If this belongs to you, describe the contents or the dolphin pin to confirm and I’ll get it back to you.
