You cannot put it in Client/Startup Script directly because the editors are not created yet. You may wait until the form is initiated, e.g. in Startup Script

currentForm.on("initiated", () => { ... your code ... }); // This example assume normal pages such as the Add/Edit page of a table

currentForm.on("initiated", (e) => { 
    document.addEventListener('focusin', (e) => {
        if (e.target.closest(".tox-tinymce-aux, .moxman-window, .tam-assetmanager-root") !== null) {
            e.stopImmediatePropagation();
        }
    });
});

i use this code in global startup script, it worked. thx.
