```
console.js:13 Warning: Function components cannot be given refs. Attempts to access this ref will fail. Did you mean to use React.forwardRef()?

Check the render method of `@mantine/core/PopoverTarget`.

Locate AdminEmbedMenu and ViewFooterSharingButton, then inspect how the latter is passed to Mantine's PopoverTarget. Reproduce the console warning in the embed menu and trace the ref usage. Done means the warning no longer appears and the menu still works.
