There are two ways for employees to access a voting campaign or a call for projects you are running :
By accessing it directly from the link of the voting campaign or CFP (in an email campaign for example)
By visiting the platform and in this case, the admin needs to create an external content to be displayed on the homepage, redirecting to the campaign or CFP
Creating an external content will allow you to highlight an action on your home page so that collaborators landing on the home page will see and access the content you wish to promote.
