Suggested approach for bend sheet metal panel with tabs

While trying to design a cover for a box I am struggling to find the best approach.
Hope you can help me out / point me in the right direction.
I have the following box out of sheet metal. I want the parts to be lasercut and machine bend. I can just upload a step file.
The light blue panel on the right hand side will be welded in.
The dark blue panel needs to be bolted in.
Due to the fact that I need to be able to insert a frame into the box, the mounting tabs/flanges cannot be on the box itself.
Furthermore the box needs to become (almost) airtight.
Therefore I started with a sheet metal pane and started adding flanges.
However, that does not work out. Even if I remove overlap in the flanges and try to use 'move plane' onshape concludes the sheel metal model is no longer unfoldable to cannot be generated.
Another approach could be to first design a flat panel with flanges, create cut-outs where the three bends needs to come and then bend it. But I cannot find a way to do the last step.
Thanks in advance for any input!

Glad you figured it out.
Another method would be to extrude that to be as thick as the tab. Then use Sheet-Metal "convert", then just tell it to ignore the bottom faces.
Having to select each of those edges around the perimeter can sometimes be volatile, because edges are not as strong as faces.
I've been having trouble with more complex geometry where the flanges would flip there normal, or the edge reference would move to an unusual place.
Just food for thought, keep that in mind if the flanges ever turn red on you
