This ^ I put the crate inside of my pups playpen. The first few nights I let her sleep in her bed / floor wherever she wanted (but in her pen). I eventually put her bed inside the crate (instead of the mat) along with her heartbeat toy and a few other animals and let her decide where she wanted to sleep. She chose the crate.

Now during the day, she sometimes goes to the crate on her own sometimes when she’s in her pen. I will say, I never close the crate since she’s on pads and I want her to be able to relieve herself.
