• Import IconButton from the public @storybook/components package instead of the internal path to avoid relying on unstable internal APIs.

import {IconButton} from 'storybook/internal/components'

packages/react/.storybook/manager.jsx:2

• Use the public @storybook/components package for IconButton, WithTooltip, and TooltipLinkList instead of importing from internal modules.

import {IconButton, WithTooltip, TooltipLinkList} from 'storybook/internal/components'
