Transferring paper share certificates into Trading212

I have a cash ISA plus an Invest account with Trading212. I want to trade UK plc paper share certificates I have from many years back. First, I need to get these from paper into electronic form.

To do this, can I submit a Crest Stock Transfer Form to the share registrar, giving them my T212 Invest Account ID? Is there more to it than this?

Newby here, any help appreciated :slight_smile:
