With TinyMCE 5.x and older, I used to be able to run editor.setMode("readonly"), adjust editor.settings.toolbar and then call editor.setMode("design") to be able to reconfigure toolbar contents after the editor.init() had already been run. I already figured out that editor.setMode() has been replaced with editor.mode.set().
However, the whole editor.settings API seems to have vanished and TinyMCE 6.x documentation only shows toolbar examples with init(). I cannot notice any info about this API being removed in migration guide at https://www.tiny.cloud/docs/tinymce/6/migration-from-5x/ either. The editor.settings has documentation for TinyMce 5.x at https://www.tiny.cloud/docs/api/tinymce/tinymce.editor/
Is it possible to reconfigure TinyMCE 6.x options toolbar or plugins after editor.init() has already been executed?
