'tel:{phonenumber} link in adaptive card not working in channel in Microsoft teams

I have used search extension query based command in Microsoft teams to render result set And as a result set Adaptive card is getting displayed. On click of a button on adaptive card I have added tel link

      {
        type: 'Action.OpenUrl',
        title: 'Call Mobile',
        url: `tel:${contact.phone_number}`,
      },

The link is working fine if I click it from chat section but it is not working fine if I click from channel section. PFA screenshots for the same
