The fundraiser type of posts is not new for Facebook but it is marked as new for Facebook groups. Notably, you can select the "Raise money for a personal cause" option that will bring you to a wide list of different options. This option is also not available on the web version.
Some of the options allow you to raise money for your business or a project so you can simply organise a Kickstarter over there. You will be able to set the title, description and the desired amount.
Unfortunately, your attempt may fail because Facebook either has a bug in this feature either they run automatic checks on the content that you are trying to post and these checks block your attempts. You will either see the creation hanging, either it will just discard the post bringing you to the previous screen.
This feature likely is an A/B test that got prompted to more users but if you have it too, let us know in the comments!
