Distrubuting apps on Testflight (Mac Catalyst)

Apologies if this is not the best place for this question, but i'm not sure where else to post. It concerns Testflight.

If I enable "Test iPhone and iPad Apps on Apple Silicon Macs".

The email the user receives still talks abou iOS. I'm assuming that because Catalyst app are in fact "iOS" Apps but the message is confusing. Can this be changed?
If I send the invite with "Test iPhone and iPad Apps on Apple Silicon Macs" disabled, then later enable it, do I have to resend the invite or the the link in the invitation email allow the user to install the app on Macos?

Again apologies if this is the wronge place.

I don't find Testflight the easiest site to use.

Can I add a blinking cursor to a TextField when using a custom keyboard?

I have a TextField in my app that triggers a custom number pad when active. Everything works great, and looks better than the system number pad ;-) but i've lost the blinking cursor. How can it add it back?

The below code is for the inputField that includes the TextField and the custom number pad.

func inputField(name: String, text: Binding<String>, unit: String, infoText: String) -> some View {
    HStack {
        Spacer()
        Text(name)
            .frame(width: 131, alignment: .trailing)
        TextField("input value", text: text)
            .hideKeyboard()
            .padding(5)
            .border(Color.gray, width: 0.5)
            .frame(width: 100)
            .onTapGesture {
                self.editingField = text
                self.isEditing = true
            }
        Text(unit)
            .frame(width: 50, alignment: .leading)

Question

Mystery challenge 2: how to animate in live activities?

I've recently went on to explore animation in widgets and seems like it was a creative solution of using timers and fonts.

But then I encountered another mystery. How do you animate in live activities? Because it seems Text(.timer) itself doesn't even animate in live activities (it just says "In 15 minutes...").

I've seen apps been able to update around 1 fps. How is this done? I don't think you can call Activity.update() every second. Also it wouldn't run in the background all the time anyway?

Here's an example of Apple's own WWDC video with a bar animating
