Final answer:
To find and edit Liam's poster on OneDrive, use the search function or browse files looking for relevant keywords like 'poster' and Liam's name. Edit the poster as needed and save the changes for shared access.
Step-by-step explanation:
To find the poster from Liam so you can make the changes Indie gave you, locate the file on OneDrive that likely contains Liam's name or a title suggesting it is the poster file. For instance, you might look for words like 'poster', 'project', 'Liam', or any other relevant keyword that might have been used when naming the file.
Once you locate the file, you can download or edit it directly on OneDrive if the platform supports the file format. If required, you could also use the search function available in OneDrive, which would allow you to find files by entering keywords related to the file you are looking for. Remember to save any changes you make so that the updated version is available for all individuals with access to the file. After making the appropriate edits, you could also share the modified file with Indie to ensure that the changes meet the given requirements.
