The sea level could have been lowered, or a volcano could have become extinct, or a coral reef could have formed, forming an archipelago and a lagoon.
By volcanoes under the sea that get bigger and bigger - and become islands..
Yes, it's the way the Hawaiian Islands were formed.

Volcano Islands are the remains of dormant or still active volcanoes that have formed islands of land above the surface of the sea.

The most southerly island of the Windward Islands in the Caribbean Sea is Trinidad. There are 14 islands in this group and most were formed from volcanic activity. Barbados is essentially a huge mass of coral.
Due to volcanic eruptions forming islands along a weakness in a long line of the sea bed, the Hawaiian Island chains was formed.

Most islands in the South Pacific were formed through volcanic activity, where magma from the Earth's mantle rises to the surface, creating new land. Additionally, some islands were formed by coral reefs growing on submerged volcanoes or tectonic activity where tectonic plates shifted and caused land to rise above sea level.
The Hawaiian Islands were formed by volcanic activity originating from a hotspot in the Earth's mantle beneath the Pacific tectonic plate. As the plate moved northwest over the hotspot, a series of volcanoes formed, creating the islands. As the plate continued to move, new islands formed in the chain, with the oldest islands towards the northwest and the youngest towards the southeast.
The Hawaiian Islands were formed by volcanic activity, as the Pacific tectonic plate moved over a hot spot in Earth's mantle. A chain of volcanoes formed as the plate moved northwestward, with new islands being formed over millions of years. The islands continue to be shaped by volcanic activity, with the Big Island of Hawaii being home to active volcanoes like Kilauea.
