Expected behaviour

I want to write a extension, but I don't know how to implement preview. I haven't written any plugins before, this was written with the help of GPT

function! leaderf#showtab#source(args) abort "{{{
    let tab_list = []
    let current_tab = tabpagenr()    

    for tabinfo in gettabinfo()
        let tab_num = tabinfo.tabnr
        let buf_name = bufname(tabinfo.windows[0])
        if buf_name == '' 
            let buf_name = '[No Name]'   
        endif
        let tab_name = printf("%d: %s", tab_num, buf_name)
        call add(tab_list, tab_name)
    endfor
    
    return tab_list
endfunction "}}}


function! leaderf#showtab#accept(line, args) abort "{{{
    let match = matchstr(a:line, '^\d\+')
    if match != ''
        let tab_num = str2nr(match)
        if tab_num > 0 && tab_num <= tabpagenr('$')
            execute 'tabnext' tab_num
        else
            echo "Invalid tab number: " . tab_num
        endif
    endif
endfunction "}}}
