clients widget

Hi,

I’m new to wordpress and having trouble adding clients to the clients widget in Moesia.

I’m adding it to a front page, using a page builder, but once I’ve added the widget and clicked ‘edit’, it says “In order to display this widget, you must first add some clients from the dashboard. Add as many as you want and the theme will automatically display their logos in a carousel.”

Please can someone help me figure out which dashboard this is this describing? And how to add said clients? Only I can’t see any option anywhere to further customise this widget/add clients…

Thanks in advance!
