Can’t Add Table Button to TinyMCE Editor

I’m trying to add a table button to a TinyMCE editor implemented on a custom option page with the wp_editor() function, but I’m having trouble initiating the table plugin. This error box shows up every time:

Failed to initialize plugin: table

And here are the functions/filters I’m using:

function tinymce_add_table_btn($btns) {
	array_push($btns,"table");
	return $btns;
}
function tinymce_add_table_plugin($plugins) {
	$plugins["table"] = "path/to/plugin.min.js";
	return $plugins;
}
function tinymce_mod() {
	add_filter("mce_buttons","tinymce_add_table_btn");
	add_filter("mce_external_plugins","tinymce_add_table_plugin");
}
add_action("admin_init","tinymce_mod",99);

I took the table plugin directly from the self-hosted TinyMCE release (v5.7.0), and WordPress has no problem detecting it; however, the JavaScript console spits these errors out:

Failed to initialize plugin: table TypeError: e.ui is undefined
Uncaught TypeError: xf.browser is undefined

I followed this article for my code, and it shouldn’t require anything extra. Help would be appreciated!
