@cvp It wasn't my Thread 😛

But you are right Phone calls and WhatsApp are different things.
Maybe there is a url scheme for whats app, or a action for Shortcuts.

But back to what i'm interested in (call shortcut and return to pythonista)
This could work:

import ui
import webbrowser

class cUIView(ui.View):
    def __init__(self, *args, **kwargs):
        self.width, self.height = 200, 200
        self.background_color = 'silver'
        
        self.vBtn = ui.Button(title = 'test', name = 'btntest')
        self.vBtn.frame = (50, 50, 100, 100)
        self.vBtn.background_color = 'white'
        self.vBtn.action = self.btnAction
        self.add_subview(self.vBtn)
        
    def btnAction(self, vSender):
        url = 'shortcuts://x-callback-url/run-shortcut?name=testBluetoothOff&x-success=pythonista3://'
        webbrowser.open(url)

vView = cUIView()
vView.present('sheet')

good argument

There is also an automation, when App is open.

@cvp
uuups, sorry. I was too busy today 😇

Maybe he means a Homescreen Symbol.
@Python567, see here, if yes:

shortcuts
But you need to install Pythonista for each User.

I know tastenform but never heard the plural.
(btw. plural is in the word tasten)
And 'operating aids' sounds like my iPad has Aids but is still operating.😷😛

In german its named: Tastenformen
(einstellungen / bedienungshilfen / anzeige & textgröße / tastenformen)

Never heard this before, i think Apple create a new word....

You can also add Unicode superscripts to the characters: \u00B2
for more information see here: Wikipedia

Result is something like this:

print(''.join('m/s' + '\u00B2'))
print('m/s\u00B2')

I'm missing the Categories for SF Symbols.
I think there are only Categories in the Mac App.
I found two older version and a Screenshot for the new Gaming Cat.
I add some cats for newer Symbols, but didn't finished.
This is what i have (with Pythonista Symbols and Emojis)

Icons.json

Names of restricted Symbols are here:
/System/Library/CoreServices/CoreGlyphs.bundle/symbol_restrictions.strings
(also a plist file)

If someone interested in a list of string, here we go

import plistlib
import io

vFilePath = '/System/Library/CoreServices/CoreGlyphs.bundle/symbol_order.plist'

with open(vFilePath, 'rb') as vFile:
    vFileObject = io.BytesIO(vFile.read())
vJsonSFSymbols = plistlib.load(vFileObject)

for vIndex, vJsonSFSymbol in enumerate(vJsonSFSymbols):
    print(str(vIndex).zfill(4), vJsonSFSymbol)
