Setting resource-id or content-desc in native app developed with typescript

We are currently testing one native application that developed in typescript, when tried to inspect it with the Appium desktop

  • we are not getting resource-id (attribute is also not showing up in inspector)
  • and accessibility id (we get the attribute but not values)

for any of the elements that present in the UI, as discussed with developers they are not aware that which tag or key in the typescript can set these resource-id or content-desc for us in the inspector, can any one suggest on this please?

Thank you.
