Water it but don't drown it and then cross your fingers. Nothing else to do. You are into Spring so it's a good time to hope for new growth.

Yup, there is no magical concoction at this point, but since the plant appears to retain some life, it may re-leaf at a later date. So just keep moist-not saturated-and see what you see. BTW, for a potted plant, that pot is its whole world. Just went through this with somebody who had ordered a bunch of desert-hardy drought-tolerant plants from a well-known vendor of same. Because the ad copy in the catalog touted these species ability to withstand weeks and months of zero rainfall once established, this person erroneously decided they could be neglected for similar stretches of time....still in their itty-bitty 2.5 and 4.5 inch pots. Let's just call this a steep learning curve-for that individual. Those plants are, of course, dead.

Thanks. Will cutting the dead stem of help with it chances of re leafing?

No. Leave it alone until it is quite clear which bits are dead. Removing the dead parts is purely aesthetic. They don't hinder new growth.
