Howcan I create a toolbar button that only shows up in the markdown editor (not the RTE toolbar)?

From my plugin:

await joplin.commands.register({
			name: 'CreateButton',
			label: 'Creates a button.',
            enabledCondition: 'markdownEditorPaneVisible && !richTextEditorVisible',
			iconName: 'fas fa-code',
			execute: async () => {

                let selectedText = (await joplin.commands.execute('selectedText') as string) || "Button Text";
                const insert = isStringEmptyOrNull(selectedText);

                const result = await dialogs.open(handle);
                if (result.id === "cancel") {
                    await joplin.commands.execute('editor.focus');
                    return;
                }

                const res = result.formData.fm_button_form;
                const hasLink = !isStringEmptyOrNull(res.button_link);
                const openingMarkup = `<span class="fm-enhanced-link ${res.button_color} ${res.button_size} ${res.button_font} ${res.button_arrow}">`;
                const finalElement = hasLink
                    ? `${openingMarkup}[${selectedText}](${res.button_link})</span>`
                    : `${openingMarkup}${selectedText}</span>`;

                await joplin.commands.execute(insert ? "insertText" : "replaceSelection", finalElement);
                await joplin.commands.execute('editor.focus');
			},
		});

        await joplin.views.toolbarButtons.create(
            'CreateHTMLButton',
            'CreateButton',
            ToolbarButtonLocation.EditorToolbar,
        );

The await joplin.views.toolbarButtons.create function adds the button to both the RTE and MD Editor. I only want it visible in the MD editor. How can I do this? Is it possible?

Thanks for any help!

I think it's not possible. Moreover - markdownEditorPaneVisible gives me errors in mobile version of Joplin.
