Redirect custom taxonomy terms archive to page - wordpress

Question

I wish redirect my terms template to a page with the save slug (to allow the client to custom the page and use a template model for this page), this is my code
function redirect_archive_term() {
$categories = get_terms( array('taxonomy' => 'chapters') );
foreach($categories as $category) {
if( is_post_type_archive( $category->slug ) ) { // like chapter-1, chapter-2 ...
wp_redirect( home_url( '/'.$category->slug ), 301 );
exit();
}
}
}
add_action( 'template_redirect', 'redirect_archive_term' );
this is doesn't work because of the condition I think, there a way to target them ?
Thanks for the help :)

Should be pretty straight forward. The following is untested.
Function has to fire before the header is deployed, thus the use of the wp hook.
is_tax() can fire on search or archive page, we need to filter that out, thus ! is_search() && ! is_archive().
We get the current term from get_term() and we redirect through wp_safe_redirect().
<?php
/**
* Redirect term page to the corresponding custom slug page.
*
* #see https://stackoverflow.com/questions/71266569/redirect-custom-taxonomy-terms-archive-to-page

*/
add_action( 'wp', 'wpso_71266569' ); //hook into wp's init action hook
if ( ! function_exists( 'wpso_71266569' ) ) {
function wpso_71266569() {
//Let's make sure we're on a taxonomy "chapters" page:
//Either taxonomy-{taxonomy}.php or taxonomy-{taxonomy}-{term}.php.
if ( ! is_search() && ! is_archive() && is_tax( 'chapters' ) ) {
$term = get_term( get_queried_object_id() ); //Retrieve the current term slug.
wp_safe_redirect( home_url( trailingslashit( $term->slug ) ) ); //eg: Redirect to https://example.com/term_slug/.
};
};
};
