Adding more compute power to my models endpoint

So i wanted to see if I could add more computing power to my models endpoint. and so, i created a Deployment Resource Pool. My issue is having my models endpoitn access these resources I created. I tried doing it via CLI and encountered some issues. I looked at the docs and that pop up option to add deployment resources pool to my fine-tuned-gemini model doesnt show up. Is it because only certain models can access the Deployment Resource Pool? The attachment shows what is suppose to pop up but that option to select “deployment resource pool” never comes up. please help
