You can make a server with a tutorial on youtube then put your world in the server for bedrock you put it where you can download it and then you download it and put it in your server folder, hope this helped you if you need more help ask me.
the first one is for java
I have a server with mini games and things I may give you my maps plugins and things.
Also best host for bedrock and java free is aternos.org
I use my computer to run my server if you want to go premium use pebblehost or apex to do it if your using aternos I won't be able to give you my minigames maps and plugins but its good too hear you know understand how to make a server now.
