Can any Sales rep access Opportunity Influence Analyzer w/o Marketo Access?

Hi,

We already have the Opportunity Influencer Analysis integrated on our SFDC opportunities. If any Sales rep clicks the Opp Analysis icon in the SFDC opportunity, can they view the Analyzer? Or do I need to give each sales rep access to Marketo (Only give them Analytics access in Marketo)?

Thank you,
