Revive Minecraft Village?

I play Minecraft on my mobile phone and my village only consists of one villager and I wanted to ask if you can do something, the new one is coming or is it not possible? Maybe it is also because there was no field in the village and they starved to death or were simply killed by monsters. Which edition do you actually have in Minecraft on your mobile phone?

Bedrock Edition.

Two options spontaneously come to mind:

You get a second villager from another village using rails and a lorry, the two should then multiply.
You look for a zombie villager and turn him back into a normal resident.
