Honestly this varys but here are some examples and tips!!
you should always tell your listeners the following:
Your name, Your position, Brief background information, Interests, hobbies or passions, A closing statement relevant to the meeting
Heres an example!
"Greetings everyone! The title of my job is _X_, and my name is _Y_. Ive worked at this corporation for 2 years. From a ___ to my current position was a gradual progression. [here is good to state information about yourself] [ then talk about your promotion here]! My excitement is building as I prepare to share details about our next undertaking with you all."
Although its a rusty example I hope it helps give an idea!!!
