How to use the @fluentui/react.ChatMessage.slotClassNames function in @fluentui/react

import { Button, ChatMessage, ChatItem } from '@fluentui/react'

const classNames = {
  threadedMessage: {
    thread: `${ChatMessage.className}__thread`,
    threadBody: `${ChatMessage.className}__thread-body`,
    innerContent: `${ChatMessage.slotClassNames.content}-inner`,
    author: `${ChatMessage.slotClassNames.author}-inner`,
    timestamp: `${ChatMessage.slotClassNames.timestamp}-inner`,
  },
  threadReplies: {
    trigger: `${Button.className}__reply`,
    message: `${ChatMessage.className}__reply`,
    gutter: `${ChatItem.className}__reply__gutter`,
    chatItem: `${ChatItem.className}__reply`,
    chatItemMessage: `${ChatItem.slotClassNames.message}-reply`,
  },
  replyEditor: `${ChatMessage.className}__reply-editor`,
}

export default classNames

import { Button, ChatMessage, ChatItem } from '@fluentui/react'

const classNames = {
  threadedMessage: {
    thread: `${ChatMessage.className}__thread`,
    threadBody: `${ChatMessage.className}__thread-body`,
    innerContent: `${ChatMessage.slotClassNames.content}-inner`,
    author: `${ChatMessage.slotClassNames.author}-inner`,
    timestamp: `${ChatMessage.slotClassNames.timestamp}-inner`,
  },
  threadReplies: {
    trigger: `${Button.className}__reply`,
    message: `${ChatMessage.className}__reply`,
    gutter: `${ChatItem.className}__reply__gutter`,
    chatItem: `${ChatItem.className}__reply`,
    chatItemMessage: `${ChatItem.slotClassNames.message}-reply`,
  },
  replyEditor: `${ChatMessage.className}__reply-editor`,
}

export default classNames

import { Reaction, ChatMessage } from '@fluentui/react'

const selectors = {
  chatMessageContent: `.${ChatMessage.slotClassNames.content}`,
  reaction: `.${Reaction.className}`,
}

const config: ScreenerTestsConfig = {
  themes: ['teams', 'teamsDark', 'teamsHighContrast'],
  steps: [
    builder => builder.click(selectors.reaction).snapshot('Clicks the first reaction'),
    (builder, keys) =>
      builder.keys(selectors.reaction, keys.tab).snapshot('Set focus on the second reaction'),
  ],
}
