Hi Team

I am working on Preview mode,

I have a page and I would like to create a preview for each component(header, footer, banner, content1 content2) of the page so kindly let me know if there is any wat to get it.

getEntry() -> I have tried this method but I am not getting nested data with it
getEntries() -> with This method I am not getting data for specified entry id

Kindly Help me, If any solution is there to achieve it.

Thanks in advance :)
