To create a slideshow with 2 embedded videos in WordPress, you can use the following example. Replace the src attributes with the URLs of the videos you want to embed.

<!-- wp:gallery {"ids":[101,102],"columns":1,"linkTo":"none"} -->
<figure class="wp-block-gallery columns-1 is-cropped">
    <!-- wp:video {"id":101} -->
    <figure class="wp-block-video"><video controls src="https://www.youtube.com/watch?v=qmZ7EPOBpnY"></video></figure>
    <!-- /wp:video -->

    <!-- wp:video {"id":102} -->
    <figure class="wp-block-video"><video controls src="https://www.youtube.com/watch?v=44dJwP1AXT8"></video></figure>
    <!-- /wp:video -->
</figure>
<!-- /wp:gallery -->

This code will create a slideshow with two embedded videos. Replace the src URLs with the links to your own video files.

<!-- wp:gallery {"ids":[101,102],"columns":1,"linkTo":"none"} -->
<figure class="wp-block-gallery columns-1 is-cropped">
    <!-- wp:video {"id":101} -->
    <figure class="wp-block-video"><video controls src="https://www.youtube.com/watch?v=qmZ7EPOBpnY"></video></figure>
    <!-- /wp:video -->

    <!-- wp:video {"id":102} -->
    <figure class="wp-block-video"><video controls src="https://www.youtube.com/watch?v=44dJwP1AXT8"></video></figure>
    <!-- /wp:video -->
</figure>
<!-- /wp:gallery -->
