My recovery contact is labeled pending for some reason

Hello dharati81,

Welcome to Apple Support Communities!

We can help resolve the issue to confirm her as the recovery contact.

Use these steps to accept the invite from her Messages app:

"How to become an account recovery contact

To become an account recovery contact, a friend or family member first has to invite you. When they send the invitation, you see a notification in the Messages app on your device. If you're part of their Family Sharing group, you're added as their recovery contact automatically. If not, you'll be asked to accept or decline this request. 

You can remove yourself as a recovery contact at any time in Settings on your device."

This Apple Support page has the full details: Help a friend or family member as their account recovery contact - Apple Support

This should help her accept the invite since it's still pending to complete the process. Please let us know if you have further questions.

Cheers!
