As for now there is no native support for Emojis in the normal community posts.

It is possible in the comments, but not in post. A workaround is to press control + command + space if you are on Mac or on windows pressing Windows + . (period) to open the system emoji tab. But this is a clanky workaround and without knowing that shortcut nobody will use.

So please add this Emoji Icon next to the Community Post icons (like uploading images, videos, audio and so on).

Thank you!
