Opening a Block's Inventory using a Command

Hi! was hopping for some advice (or letting me know if its even possible). I have a block, its purpose is to hold items and distribute them. what i would like is to have a command to open its GUI without needing to click on the block itself. ive set up the command to take the chords of the block but nothing i do will open it itself. simulate right click did nothing, open screen for that block opened the GUI but not with its inventory
