Signatura in documents for Maui .net

I need a component where a user will be able to upload word/pdf file the app needs to collect the user signature either via Writing with finger/pen or uploading png/jpg and select in the document where it will need to be placed the signature, once it was done the app will generate a new file word/pdf with the signature placed where the user selected in the file

in the app the developer//freelance needs to delivery a Maui .net project demo, very simple, like a default visual studio project with the code for the signature module and with this working in for test, no login, no publishing just the signature component working
