Cannot redirect user to Branda's login page

Hi, I've been in touch via chat to resolve an issue with redirects. We were unable to successfully redirect /my-account pages to the Branda's custom login page. When the user accesses the /my-account, the theme's standard login page appears, however, we need to redirect the user to Branda's login page.
There's a redirect in functions.php to Branda's login page (for password reset):

add_filter( 'lostpassword_url', 'my_lost_password_page', 10, 2 );
function my_lost_password_page( $lostpassword_url, $redirect ) {
return 'https://example.com/login?action=lostpassword';
}

However, we need to redirect the user from /my-account/* to Branda's login page too.

Thanks!
