Hello togehter i have a little issue in my Power App.
The goal is to save signature in the App for example:
in this field i want to have a signature

I signature it

then i can save my signature
and the signature is seen in my Sharepoint-List


but my problem is, when i open this sharepoint element again i can't see my signature and i can sign again which should not be the case

as you can see the signature field is empty.
What is my problem and how i can solve it?
