[DenysMyrosh]

Description:
Given a patient has booked a telemed call and is on the waiting screen, when the patient clicks on Manage Participants > Add participant with all required data filled, then the participant should be indicated as added in the call and receive an invite link but instead we get error "InviteParticipantForm.tsx:27 Error: video chat create invite zambda environment variable could not be loaded" is shown in the console.

2. Proceed to the waiting room screen from the intake flow
3. Click on Manage Participants
4. Fill in all required participant details.
5. Click "Add participant." to invite the participant.

Participant is added to the call, and an invite link is sent.

Actual Result:
The participant is not added, and the error message: "InviteParticipantForm.tsx:27 Error: video chat create invite zambda environment variable could not be loaded" is shown in the console.
