HELP beginner Premiere Pro struggling to use the templates

I have just subscribed to Envato Elements to make life easier but don’t seem to be able to use any of the video templates that I have downloaded. For example, the help videos show that there is a final sequence in the timeline tabs but I don’t seem to have that.
Is there somewhere that I can get a slowed down version of help with these templates? I feel that I have wasted my money so far.
