i cant find simplify tool in my inspire 2024 version , how can i find it ?

You can access the tools in three different ways;
1- In Modify, from the drop-down menu on the Partition icon 

2- Type the command name in the search field in the upper right corner of the software

3- With the Toll Belt ( Alt+ RMB )

Thanks M.R Hakan for considering time towards my problem and giving a solution for it. I am happy that my problem is solved. Once again a heartful thanks to you for helping me.
