Help/question with Spacebar sms/mms app

Hello, I am running Mobile Plasma 5 on Mobian/Pinephone. I’m using the Spacebar app for sms/mms messaging, as it’s linked with Phonebook.

After sending a couple test texts, I noticed that there is no spell-check or word/auto suggestion/fill (or whatever it’s called). I checked the settings (top right) and there doesn’t appear to be either of these.

Does plasma (mobile) have another linking app/widget that does this or is this something that needs to be enabled in the settings panel?
