How to make a single link in header open in new tab?

I’ve created a dropdown menu called SHOP OUR BRANDS.

it has 5 submenus, and all those 5 submenus are linked to external websites. Those websites are part of our company.

What I need help with is, when I try to open any of the submenus, they open in the same window/ tab.

I want it to open in a new tab/ new window.

How to implement that.

Please do help.

Thank you in advance.
