Hi @jeromeespere,

Welcome to the forums! Please check out theme documentation, then contact theme author for support if something’s not covered:

If the feature you are looking for is not available as standard theme option, you may need to hire WordPress professional to make changes to theme code.

Thanks,
Luca
