1 year old cavapoo won’t eat her kibble

hey guys, I have a cavapoo whose previous owner only ever fed her cooked human food steak and similar. Im trying to transition to kibble per the vets recommendation but it’s been difficult. As she is even picky with her treats.

My method: I put the kibble down for 10 minutes and if she doesn’t eat I pick it back up and wait until the next mealtime. The first 3 days she refused kibble completely and around day 4 she started eating a little, but never her full daily requirement she needs about 70g a day and is not even eating closer to 20g. This has been going on for one to two weeks now. i don’t know if i should just give up and start feeding her what she wants.

She’s otherwise healthy,energetic, normal, drinking, normal poops. So I don’t think she’s sick. I think she just doesn’t see kibble as real food after a lifetime of steak.
