In my area of AZ, I start them outside the first few days with almost ZERO direct sun, all dappled sun through shade mesquite branches, or under the eaves of the house. After about 3-4 days (watch for stress or stretching), I move them to just a couple hours of direct sun a day. IF they tolerate that, another couple of days then full sun. They will dry quickly in our 11% RH outside, so monitor the soil! After that, I put them in as much direct sun until mid/late April, then time to really watch for stress as it gets hot.
May one suggest a cheap light meter and some shade cloth be one of your next steps in prep for your outdoor area? I ordered a custom-sized piece from these people. https://www.becoolsolutions.com/products/white-knitted-shade-cloth
Krylon makes a plastic paint called Fusion that bonds well to grow pots. (Rustoleum plastic paint is okay if the pots aren’t traditional smooth grow pots) Maybe paint the outside of your pots before it gets too hot (doing mine over next few days).
I have grown small amounts successfully outdoors in Arizona and that is my approach. Others from hot climates may have a different way.
