Pull request overview

This PR adds proper pagination support to the requestGetTeamMembership function to handle teams with more than 100 members. Previously, the function only fetched the first page of team members, which could result in missing memberships if a team had many members.

Key Changes:

• Implemented a pagination loop that continues fetching pages until all team members are checked
• Added offset tracking and the "more" flag to properly iterate through all pages

The offset increment uses resp.Limit which could potentially be 0 or different from the requested limit. This could lead to an infinite loop or incorrect pagination. Consider using the requested limit (100) instead: offset += 100

Suggested change

	offset += resp.Limit
	offset += 100
