I’m trying to open up specific contacts in the windows 10 whatsapp application using vba and a Microsoft Access database. Opening these links first opens Edge and then opens whatsapp. However, Edge is always prompting that ‘A website wants to open this application’, which I need to disable for the application to work.

I’ve added the latest Edge policies (22H2) to my PC and edit them via Local Group Policy Editor: Administrative Templates -> Microsoft Edge ->Define a list of protocols that can launch an external application from listed origins without prompting the user

Here, I’ve enabled the policy and added the following as an option/protocol

[{"allowed_origins": [ "*" ],"protocol": "whatsapp"}]

The link that I’m trying to open

whatsapp://

Inside of edge I am able to see that the policy has been adjusted and the protocol has been saved using edge://policy/ and edge://settings/content/applicationLinks

However, the whatsapp link still prompts me the same message. Is there anything wrong? Did I forget a setting?
