BTG solo mining block solution

Could someone explain to me how does finding a block solution for solo mining work on BTG and the Equihash 144,5 algo?

On ETH you had to submit a share with a difficulty equal or higher than the network difficulty to get the block, but solo mining BTG I submitted shares with a higher diff than the network diff and still didn’t get the block.

Is there a way to know if a share represents a block solution by its difficulty shown in the miner software?
