SafariViewController redirections not happening when parent app is in background

I am using Safari View Controller for IDP authentication. IDP being used is Microsoft and two factor auth is being used through MFA iOS app.When we approve from from MFA app and our app is in background then after "Approve" Safari redirections are not successful. On the other hand if we approve by interactive notification then redirections are successful which is understandable as app stays in foreground.This issue comes only when app is in background. Both the behaviours are captured in attached video.Please late me know if anything else is needed.
