# Media replace flow

A component that implements a replacement flow for various media objects. It is used to allow various blocks that use media to have a toolbar button for replacing it. I offers several options, such as:

-   replace from Media Library
-   replace using an URL
-   replace by uploading new media

This component should be used as a child of a `<BlockControls>` component.
