The all-sided pore mushroom block

Hi, I do a big project with my university on Minecraft, until now, I used one of the block which is the all-sided pore mushroom block. But after the update in version 1.21.40, this block has been removed. I really need this block to finish my project, and it is really important for me to have this block back. I even feel despair without this block, and I didn’t find any other solution, so this is why I post here. I will be very grateful if this block can be added back to the inventory ! Thank you for reading my post !
