Hi Mahinnisa,
Native apps only support those two options. Since Native apps are “Offline First” microflows are not possible anyway and Nanoflows are not supported as navigation options. If you want to trigger logic while opening the page you might want to try the microflow timer and add a nanoflow on the page once it opens, you can select “Execute once” and the nanoflow will be triggered when the page is opened.
Cheers!
