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. In order 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
