Insert text in sg.Multiline from external Keyboard - input

Question

Dears,
I'm wondering if there is a way to Insert text in sg.Multiline from external Keyboard ( Virtual On-Screen Keyboard):
it's working for sg.Input :
if isinstance(element, sg.Input):
if element.widget.select_present():
element.widget.delete(sg.tk.SEL_FIRST, sg.tk.SEL_LAST)
element.widget.insert(sg.tk.INSERT, event)
And not the case with sg.Multiline:
if isinstance(element, sg.Multiline):
if element.widget.select_present():
element.widget.delete(sg.tk.SEL_FIRST, sg.tk.SEL_LAST)
element.widget.insert(sg.tk.INSERT, event)
I got the following error message : AttributeError: 'Text' object has no attribute 'select_present'
The Remaining Issue :
The above issue is fixed and once I want to delete characters from "sg.Multiline" it's going directly to "except" part , below is the script used. Could you please advice ?
elif event == "DEL" :
try:
element = window.find_element_with_focus()
if element.widget.tag_ranges("sel"):
element.widget.delete(sg.tk.SEL_FIRST, sg.tk.SEL_LAST)
else:
insert = element.widget.index(sg.tk.INSERT)
if insert > 0:
element.widget.delete(insert-1, insert)
except:
sg.popup("Error")
Thanks in advance
