She's failing in her duty and not doing a big chunk of her job which is supporting her team.
The 1-1 is her chance to check in with you, to give well done feedback that will motivate and encourage you to continue delivering, and developmental feedback that will help you stop / start / improve where you need to.
And your chance to share what you've done, highlight success, ask for support.
And it's about fairness. If you're ambushed at midyear or end of year with a less than glowing performance appraisal, she has been unfair.
Start formally requesting 1-1s, face to face or Teams.
Come with your notes on your achievements and delivery notes ready to discuss.
Actively seek out feedback.
Make notes and share them with her as a record of what happened.
If she refuses, note that too.
It might be wuse to check organisation policy on management behaviour - is she doing what she should? If not - speak to her LM. She may be overwhelmed and need support herself.
