By default, sending messages in the communication module is done by pressing the Enter key. However, in the settings of your own user account, a send button can be activated, whereby the Enter key performs the function of a line break.

The settings of your own user account can be accessed by clicking on your own name in the lower-left corner and then selecting the menu item "Your user account ...".
Open personal settings
View the button
After the settings of the user account have been opened, a click on the tab "Account" follows. This will display the basic account settings. To display the button for sending a message, the checkmark must be removed at "Enter key to send". From now there will be a button for sending the messages in the communication module. The Enter key can be used to create a new line now. Sending messages is also possible by using the keyboard shortcut "Shift" + "Enter". Comments are also sent via this key combination, while the Enter key also creates a line break here.
Uncheck "Press enter to send" to display the button
