Additional:
You might inflate & set your bead before adding sealant. It should largely hold air on it's own for quite some time. No need to encourage a messy "burp" with hasty & hurried installation.
Once you are satisfied it holds air & the tire is mounted well, deflate, remove the valve core & inject ~60ml of sealant.
Reinstall valve core & inflate to minimum pressure listed on tire sidewall.
Bounce & spin. Bounce & spin. Bounce & spin.
Inflate to ride pressure & go for a ride.
