This is sadly a numbers game, you'll need to apply a lot to increase your probability of hearing back.
Rejections/no replies can be demotivating, but aim to apply to atleast 10-15 companies everyday.
Look out for career pages of companies to see who are actively hiring.
Use keywords like "[your profile] hiring" or something similar on LinkedIn to check out actively hiring folks.
Apply well in advance, these procedures can take anywhere from 1-3 months. Don't be afraid to follow up once or twice.
Try to show what you'll bring to the table from the very start. You can do this by including a portfolio, a separate doc detailing how you can contribute.
Try to network, send in your resume to LinkedIn folks, ask if they're hiring, ask for mentorship opportunities, someone might just refer you.
