Show pagination in custom template

Hi, Thank you for your plugin.

I have a question about the pagination. I used a custom template to show eight event posts above the event calendar and I’d like to show all of the events no matter It was past. So, I created a query to retrieve it.

I tried:

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

$my_query = new WP_Query(array(
    'post_type'     => 'tribe_events',
    'posts_per_page'=> 8,
    'start_date' => "1990-01-01 00:00:00",
    'paged'         => $paged,
));

However, when I added the pagination code at the end of the wrapper. It didn’t work.
This is the theme pagination function.

<?php gullu_pagination(); ?>

then I’ve tried the method refer to Here

<?php $args = array(
    'base'               => '%_%',
    'format'             => '?tribe_paged=%#%'
); ?>
<?php echo paginate_links( $args ); ?>

and it also didn’t work.

Also, I’ve tried other coding like:
stack

The above method was able to show a arrow and link to next page, but there is nothing inside the second page… I have created nine demo events.

How can I retrieve all the events? Please give me some advice, thanks.
