Text preview for Arabic (kerning and spacing)

Is it possible to write normal connected Arabic letters in the Text Preview in Glyphs in order to properly fix the kerning and spacing?

Just type and switch to Right-to-Left mode with the buttons in the lower right.

Thanks!

As I was typing certain letters in the Text Preview didn’t appear, like the “Lam-Alef”. However, when I exported the font, it worked well. I think it’s a bug, just letting you know

For ligatures to appear, you need to activate the ligature feature form the button in the lower left.
