Question

EX: <a href="/page/category/">Button</a>

my category name: osten & my category id: 43

Answer 1

You can use get_term_link https://developer.wordpress.org/reference/functions/get_term_link/ .
For that, if you have the ID, then you can pass it to that function.
Check the documentation for this function and see what argument you can pass it

Answer 2

Maybe this can help? You can pass either name or ID

<?php
    // Get the ID of a given category
    $category_id = get_cat_ID( 'Category Name' );

    // Get the URL of this category
    $category_link = get_category_link( $category_id );
?>

<!-- Print a link to this category -->
<a href="<?php echo esc_url( $category_link ); ?>" title="Category Name">Category Name</a>
