Add snippet to functions:

functions.php

function enqueue_adobe_fonts() {
    // Enqueue on the live public website
    wp_enqueue_style( 'adobe-fonts', 'https://use.typekit.net/ztf3zqc.css', array(), null );
}
add_action( 'wp_enqueue_scripts', 'enqueue_adobe_fonts' );

function enqueue_editor_adobe_fonts() {
    // Enqueue inside the admin Block/Site Editor
    wp_enqueue_style( 'adobe-fonts-editor', 'https://use.typekit.net/ztf3zqc.css', array(), null );
}
add_action( 'enqueue_block_editor_assets', 'enqueue_editor_adobe_fonts' );
