Yammer browser and App protection policy

We have an issue that links to a forms.office.com in the Yammer app on iOS  fail to open if the browser setting to in the is set to Yammer.

We get the message that you do not have access and that you must use Safari, Intune Managed Browser or Microsoft Edge.

If we change the browsersetting in Yammer to Safari, links to forms open as expected.

I know this is caused by the app protection policies we have configured but how can i allow the Yammer browser open those links without the error.

Other solution might be to create a configuration policy for yammer to set safari as the default browser but i cannot find any documentation on how to do that.
