How can I click on each link on a page and then return to the initial page using Robot Framework?

Question

I have this link : https://pubmed.ncbi.nlm.nih.gov/?term=Fleiss+B and I want to click on each link, extract some information and then comeback to the initial page. So far I managed to make 2 for loops that go through all pages and extract the links from each page.

'''

${nrpag}  Get Element Attribute   class:page-number  max
Log To Console  ${nrpag}
FOR  ${j}  IN RANGE   1   ${nrpag}
    ${links_nr}=  get element count  xpath://a[@class="docsum-title"]
    Log To Console  ${links_nr}
    @{links}  Create List
    FOR  ${i}  IN RANGE  1   ${links_nr}
        ${linktext}=  Get text    xpath:(//a[@class="docsum-title"])[${i}]
        ${idk}=  writetextlinks  ${linktext}
        ${elements}=    Get WebElements    //a[@class="docsum-title"]
        ${href}=    Get Element Attribute    xpath=(//a)[${i}]  href
        ${p2}=  writeLinks  ${href}
         Log to console  ${linktext}
    END
    Click Button   xpath://button[@class="button-wrapper next-page-btn"]
END
