Adding reactions to messages in channels and groups is a straightforward method in various messaging platforms, with the added feature of emojis to quickly express one's feelings. Below are the steps to add reactions to messages in popular platforms.

Many platforms like Microsoft Teams, Skype, support the use of emojis as reactions. To add a reaction in these platforms, 电报官网 you'll first need to make sure that the platform in question has reactions disabled.

To add a reaction in Slack, you'll need to first identify the message you want to react to. After clicking on the target message, you'll see a list of emojis displayed below the message. From there, you can simply click on the emoji that best suits your reaction. If you cannot see the reaction emoji, you might need to hover over it so you can view the available options.

Similarly, in Microsoft Teams, to add a reaction, right-click on the message and then click 'React'. A list of emojis will appear, which you can select from. To remove a reaction, simply click on the reacted emoji again, which would have turned blue previously.
