How to add Nibiru chain to KEPLr?

Could you please explain the process of adding the Nibiru chain to the KEPLr wallet in a step-by-step manner? I'm a bit new to this and would appreciate it if you could guide me through the entire process, including any prerequisites or important considerations I should be aware of. Additionally, is there a specific version of KEPLr that I need to have in order to add the Nibiru chain, or is it compatible with all versions? Thank you in advance for your help.
