send limit of adaptive cards using microsoft flow

[nickke170]

I have a question to see if someone can guide me,
I am trying to implement a flow that sends adaptive cards to users of my organization
By means of the flow bot, the card will be sent to your team chat,
But they ask me what is the limit number of sending those cards in their case it has no limit

I put an example
I want to send a card to 1000 team users in my organization.

I have the same question. Anyone familiar with a limit on the number of adaptive cards you can send? It only shows the first 100 of the supposed 1300 users in the Office 365 group.

Any thoughts?
