Zoom on Facebook Portal

So, I see a doctor (therapist) on zoom.  She sends me a texted link to join her session on zoom.  Here’s the issue:

I started using a Facebook Portal camera on my TV.  When the text arrives on my phone, I can’t open the meeting on the TV.  

Is the meeting ID part of the text so I can put it into the Facebook Portal Zoom?  Or is her personal link name somewhere in the text?  

I don’t know if this makes sense.  Thank you to anyone who knows the answer!
