I would be happy to help.

To add electric trailer brakes to the 2021 Anvil 6' x 12' Cargo Trailer you mentioned you will need to do is verify that behind the idler hub is a brake mounting flange as shown in the included picture.

If one is there brakes can be added pretty easily, and if one is not there brakes can still be added, but it will be a bit more work.

If no brake mounting flange is installed you will need to have one installed. I was able to find that the Anvil 6' x 12' includes a 2990lb axle which likely has a 2-3/8" diameter. If that is the case then the # 4-35 would be the correct flange. This will need to be installed by an axle shop as it needs to be perfectly square to the axle to prevent premature brake wear and decreased braking performance.

Next since the axle has a 2990lb rating it would use 3500lb braking assemblies # 23-468-469.

When it comes to hub and drum assemblies you will likely need the # AKHD-545-35-EZ-K, but you will want to confirm the bearing combination first by removing one of your current hubs and looking for the bearing number stamped in the face of both the inner and outer bearings as shown in the included picture of the # L44649. This hub uses inner bearing # L68149 and outer bearing # L44649 so as long as that is what your current hub uses this would be correct. If you have a different bearing combination just let me know.

Moving on to the wiring there are a few different things you will need to add. First being a 7-way connector # H20046 and junction box # 38656. You will need to run # 10-1-1 from the junction box to the brake magnet on each of the braking assemblies as well. Second you will need to add a breakaway kit using the # C52042 which is a fail safe that automatically applies the brakes on your trailer should it become disconnected from your tow vehicle.

That completes everything on the trailer side of things, but you will need to make sure your tow vehicle has a fully functional 7-way connector and a trailer brake controller. If you are missing either of these components just let me know the Year/Make/Model and I would be happy to make a recommendation for you.

I included videos of the products mentioned and a link to a helpful article on adding electric trailer brakes for you to take a look at.
