How to add or chage tinymce config before init?

[malozaibi]

Four hours passed trying to change the config with no hope.

I read the documentation https://voyager-docs.devdojo.com/bread/introduction-1/tinymce and did set the external js and functions, but I didn't know how to add the custom config!

function tinymce_init_callback(editor)
{
    // what to do here!!!!
}
function tinymce_setup_callback(editor)
{
    // or here!!!
}

I want to change the language and direction and the toolbar etc. I can only do that in the bread option but I want it for all editos in all my breads, so js is the key.

I googled a lot with no answer.

please help, I really need to customize the tinymce config. Thanks in advance

and I want to chage the language and direction when clicked on the language selector button in the bread. Is it possible?
