OceanWP plugins activation key after install

Hi all,
I installed OceanWP theme and imported the pro template to be used but 2 of the required plugins are asking for activation key.

Plugin names are:
Ocean Elementor Widgets
Ocean Sticky Header

Pop-up after installation has message
Thanks for purchasing Ocean Sticky Header! To get started, please enter your license key:

And if not fixable. What would be a best alternative for a technology site with services,blog and ecommerce

Thanks in advance
