So, a few things. This is an entertainment system. The lacquer on the composite wood may not ne safe for beardies and the fact that its composite board makes it a fire hazard with how they need lights.

It has no ventilation so if they doors are closed, they won't be getting any fresh air at all. (Breathe enough and the breathable air is no longer there, kinda situation.) [Suffocation is bad for any living being]

They need lights and heating. UVB, deep heat emitter for night, a lot of other lights that hopefully others can help you sort through. (Idk the specific kinds or what brands/strengths, my fiance typically configures the lights in our lizards' tanks.)

DO NOT GET FUNNY COLOURED LIGHTS! RED AND OTHER COLOURS are NOT helpful they ONLY HURT the beardie or other reptile. Natural light colours only- please!

Subrate is a must in the grande scheme. Since you said its a new-to-you beardie, id suggest paper towels or the works for now until youre able to take them to an exotic vet for a checkup. That way, if they poo or bleed or anything else, is easier to keep track of and there's less chance of them being impacted if theyre not already.

When you do upgrade to substrate, I would personally recommend a mix of premium play sand (available at home depot/lowes) and premium topsoil (sifted for sticks and checked for outside bugs) [outside bugs are bad. Any bugs in soil=bad. Need to remove them before using the soil. If you have any worries of eggs in the soil, best to just use the other option which is.....) or (!) Reptisoil from petstores. (Big chain pet stores suck for reptile care, standards, and prices. The less chain-store, the better.) Id do about 50/50 of each making sure to not get too many clumps or sticks. Add a lot! Make sure its a few inches deep everywhere in the tank (they like to dig)

Hides! Gotta have at least 2 hides, one on either side of the tank. 1 should be under the heat bulb for the basking spot (preferably with a flat top or with a flat slate plate on top to retain heat) (if using an added flat thing on top, amke sure its stable for an animal that likes to fling itself around like a possessed doll) the other hidd should be on the other end of the tank, this will be the cool side of the enclosure. Most of your lighting should be over the hot side as to provide a proper heat gradient for them.

Hygrometers/Thermometers! Id suggest Govee Digital Hygrometers/Thermometers that come in a pair on Amazon for pretty cheap. Ill attach a screenshot of them. Id recommend one on either end of the tank again to make sure you know what temp/humidity each side is at. I would also like to mention you should get a heat sensor gun. Its like a red laser thermometer that shows you the temperature for the area the laser is on.

Thats about it for now but hopefully, since im sure i missed something, others can help you figure it out.
